SUMMARY:Special Physics Seminar, "Exploring Strongly Correlated Matter with Exotic Atoms, Atom Chips and Cavity QED" (Benjamin Lev, University of Illinois at Urbana-Champaign)
DESCRIPTION:Advances in the quantum manipulation of ultracold atomic gases are opening a new frontier in the quest to better understand strongly correlated matter. By exploiting the long-range and anisotropic character of the dipole-dipole interaction, we hope to create novel forms of quantum mesophases, states of quantum soft matter intermediate between canonical states of order and disorder. Our group recently laser cooled and trapped the most magnetic atom, dysprosium, which should allow investigations of quantum liquid crystals, mesophases thought to exist in, e.g., hi Tc cuprate superconductors. In addition, Dy will form the key ingredient in hybrid quantum circuts as well as in novel scanning probes using atom chips, substrates supporting micron-sized current-carrying wires that create magnetic microtraps near surfaces. We are developing a cryogenic atom chip miscroscope that will possess unsurpassed sensitivity and resolution for the imaging of condensed matter materials exhibiting exotic transport and magnetism. Finally, we will present recent theoretical work suggesting an additional route to explore quantum mesophases. We propose that quantum glasses arising from quenched disorder in fully emergent supersolids may be observable with atomic BECs in multimode optical cavities.

SUMMARY:Special Physics Seminar, "Very Weak Interactions" (Itay Yavin, New York University)
DESCRIPTION:What lies beyond the Standard Model of particle physics? Are there very weakly interacting forms of matter and forces waiting to be discovered? In this talk I will describe some of the efforts underway to detect very weakly interacting particles, from dark matter to new forces. I will discuss recent observations and their theoretical significance as well as the connection to other experimental results. I will conclude with a short summary of the different frontiers and their interrelations.

SUMMARY:Special Physics Seminar, "Quantum Information with Atoms and Light" (Steve Olmschenk, University of Maryland)
DESCRIPTION:Rapid progress in coherent control of single trapped atomic ions and ensembles of ultracold atoms in optical lattices has enabled more precise atomic physics measurements, a probe of fundamental quantum physics, and progress towards quantum information processing. Here I present recent results on approaches to quantum information with each of these systems. Using ytterbium ions coupled to single photons, we demonstrate a quantum teleportation protocol between two distant matter qubits with a measured fidelity of 90(2)%. With atoms in an optical lattice, we perform randomized benchmarking of single qubit operations, measuring an average error per gate of 1.4(1) x 10^-4. A method to extend the coherence time by cancellation of up to 95(2)% of the differential light shift in the ground state of rubidium is also implemented. Finally, I discuss how these gate operations might be extended for more advanced applications.

SUMMARY:Special Physics Seminar, "Coherent Manipulations with Ultrafast Pulses and Trapped Ions" (Wes Campbell, University of Maryland)
DESCRIPTION:The field of quantum information science promises computational methods that are more efficient than classical algorithms for certain calculations. In particular, the use of a well-controlled quantum system to simulate computationally-intense quantum many-body problems is likely to produce nontrivial results in the next couple of years. While still being a leading demonstrated quantum information architecture, the trapped atomic ion processor suffers from impediments to scaling up to more ions from the continuous wave (cw) laser mediated quantum gates that are used to perform the computation. We have recently demonstrated the use of mode-locked pulsed lasers to perform a comprehensive series of quantum information processing tasks (including an entangling gate) that allows us to circumvent the laser-induced decoherence of cw Raman transition based gates. We also realize ultrafast gates where a single laser pulse can drive a high-fidelity single-qubit gate in ~50 ps. Such high-probability population transfer from a broadband laser source opens the door for ultrafast entangling gates and rapid deceleration of atomic and molecular beams. Furthermore, the strong-pulse interactions provide a potential avenue to realize ultrafast entangling gates between multiple qubits that operate without the need to spectroscopically resolve motional sidebands and scale favorably to large numbers of qubits.

SUMMARY:High Energy Physcis Seminar, "Directional Detection for Dark Matter and Neutrino Physics" (Jocelyn Monroe, MIT)
DESCRIPTION:Recently there has been great interest in gas-filled time projection chambers for low-background physics, motivated by searches for directional dark matter detection, neutrino-less double beta decay, and neutrino magnetic moments. The unique feature of such detectors is the ability to reconstruct low energy particle tracks down to tens of keV. I will discuss the potential of this detector technology for two timely applications: first, to correlate a candidate dark matter detection signal with its astrophysical source, and second, to make the first measurement of the K-40 geo-neutrino flux.

SUMMARY:Physics Colloquium, "Computer Vision and Optics in the Study of Fine Art" (David Stork, Ricoh Innovations)
DESCRIPTION:New rigorous computer vision algorithms have shed light on a number of problems and controversies in the history and interpretation of fine art. Rigorous illumination estimation and shape-from-shading methods can reveal in new ways the accuracy and the working methods of masters such as Vermeer, Georges da la Tour and Caravaggio, including claims they traced projected images. Computer methods can dewarp the images depicted in convex mirrors depicted in paintings such as Johannes van Eyck??s Arnolfini portrait and Parmigianino??s Self portrait in a convex mirror to reveal new views into artists?? studios and shed light on their working methods. This colloquium will explore how rigorous computer image analysis and optical analysis of art is changing our understanding of paintings and drawings, also featuring works by Vermeer, Lotto, Memling, and several others.

SUMMARY:High Energy Theory Seminar, "Precision Tests of AdS/CFT Integrability from Strings in the AdS Light-Cone Gauge" (Simone Giombi, Perimeter Institute)
DESCRIPTION:We discuss some recent perturbative calculations for quantum strings in AdS5 x S5 and their comparison to integrability based results in planar N=4 Super Yang-Mills (SYM). We use a certain AdS version of the light-cone gauge, which is shown to yield considerable simplifications compared to previous approaches. In particular, we present a detailed 2-loop analysis of the energy of a long folded spinning string in AdS with an angular momentum on S5, obtaining exact matching with the Bethe ansatz prediction on the gauge theory side. This resolves a previously appeared disagreement between string theory and Bethe ansatz, and provides non-trivial evidence for the quantum integrability of the AdS5 x S5 superstring. Finally, we also use the AdS light-cone approach to compute quantum corrections to the dispersion relations of excitations above the long spinning string in AdS, and compare to recent all-loop results obtained from the Bethe ansatz.

I will discuss the theoretical motivations for these candidates, their diverse implications at the interface of particle physics, astroparticle physics, and cosmology, and the prospects for identifying dark matter in the coming years.

SUMMARY:Special Physics Seminar, "Experimental Gravity with LIGO" (Sam Waldman)
DESCRIPTION:The direct detection of gravitational waves (GWs) offers a revolutionary new probe of the most energetic processes in the universe and a test of general relativity in new regimes. The 4 km long LIGO interferometers have demonstrated the sub-attometer displacement sensitivity (< 10^{-18} m/ Hz^{1/2}) and continuous operation (> 75\% duty factor) needed to detect GWs out beyond the Virgo cluster, but none have yet been seen. Starting in 2008, we began construction of a 2nd generation of interferometers, Advanced LIGO, to increase the detector sensitivity and bandwidth by more than an order of magnitude. In this talk I will review the next five years of physics challenges and experiments involved in building and commissioning Advanced LIGO. We will discuss our plans to commission active seismic isolation systems with picometer displacement noise, low-loss passive isolation systems with mechanical quality factors >10^7, and Michelson interferometers with 750 kW of stored power. Together, these systems form a detector capable of detecting the 2x10^{-20} m GW signal from two black holes coalescing 6 billion light years away. We expect Advanced LIGO to detect the most powerful sources -- the merger of two compact objects such as neutron stars and black holes -- with rates from a few to many per year. The GW waveform, together with electromagnetic observations, will allow tests of the physics of black holes and general relativity. As the Advanced LIGO program continues, we will continue to improve the interferometer sensitivity using techniques from integrated photonics, material science, and quantum measurement.

SUMMARY:Physics Colloquium, "How to get a Superconductor out of a Black Hole" (Chris Herzog, Princeton University)
DESCRIPTION:Gauge/gravity duality, a concept which emerged from string theory, holds promise for revealing the secrets of certain strongly interacting real world condensed matter systems. Historically, string theorists presented their subject as a promising framework for a quantum theory of gravity. More recently, the AdS/CFT correspondence and gauge/gravity dualities have emerged as powerful tools for using what we already know about gravity to investigate the properties of strongly interacting field theories. I will cherry pick and discuss a few recent developments where black holes are used to calculate the thermodynamic and transport properties of quantum critical systems, superconductors, and superfluids.

SUMMARY:High Energy Theory Seminar, "SO(3) Conformal Symmetry in Hadronic Collisions" (Steve Gubser, Princeton University)
DESCRIPTION:An SO(3) subgroup of the conformal groupin four dimensions can be used to study aspects of hadroniccollisions. Two examples are the hydrodynamic flow at timeswell before freeze-out and the characterization of initial statein terms of a saturation scale. To illustrate the first example,I will explain an exact solution of the Navier-Stokes equationswith SO(3) symmetry. To illustrate the second example, I willpoint out how the same SO(3) symmetry leads to a simple ansatzfor the Balitsky-Kovchegov equation. Part of the motivation forusing this SO(3) conformal symmetry comes from AdS/CFT, but themain results can be understood without referring to the duality.

DESCRIPTION:A decade since the realization that our universe's expansion is accelerating, the ball remains squarely in the observationalists' court -- as the theorists look for more constraints on the parameter space. I will discuss some of the progress that has been made, and the prospects for upcoming advances. The supernova measurements have improved dramatically, and I will show new evidence that that they have not yet reached their ultimate capability. Combined with the advances in the other techniques, we have the hope of distinguishing alternative explanations of the accelerating universe. The next big step calls for new facilities on the ground and in space.

Featuring a large target mass and an extremely low background, XENON100 is the most sensitive dark matter direct detection experiment in operation today. Located deep underground at the Gran Sasso National Laboratory, in Italy, XENON100 has recently reported results on the elastic scattering of dark matter WIMPs with nucleons, based on 100 days of data acquired in 2010. The recent findings, the status of the experiment and the work towards the next generation XENON1T experiment will be presented.

SUMMARY:High Energy Theory Seminar, "Axion Dark Matter Detection with Cold Molecules" (Peter Graham, Stanford University)
DESCRIPTION:Current techniques cannot detect axion dark matter over much of its parameter space, particularly in the theoretically well-motivated region where the axion decay constant f_a lies near the GUT and Planck scales. We suggest a novel experimental method to search for QCD axion dark matter in this region. The axion field oscillates at a frequency equal to its mass when it is a component of dark matter. These oscillations induce time varying CP-odd nuclear moments, such as electric dipole and Schiff moments. The coupling between internal atomic fields and these nuclear moments gives rise to time varying shifts to atomic energy levels. These effects can be enhanced by using elements with large Schiff moments such as the light Actinides, and states with large spontaneous parity violation, such as molecules in a background electric field. The energy level shift in such a molecule can be ~10^-24 eV or larger. While challenging, this energy shift may be observable in a molecular clock configuration with technology presently under development. The detectability of this energy shift is enhanced by the fact that it is a time varying shift whose oscillation frequency is set by fundamental physics and is therefore independent of the details of the experiment. This signal is most easily observed in the sub-MHz range, allowing detection when f_a > 10^16 GeV, and possibly as low as $10^15 GeV. A discovery in such an experiment would not only reveal the nature of dark matter and confirm the axion as the solution to the strong CP problem, it would also provide a glimpse of physics at the highest energy scales, far beyond what can be directly probed in the laboratory.

SUMMARY:High Energy Theory Seminar, "Holographic Fermions" (David Vegh, SUNY Stonybrook)
DESCRIPTION:The most successful effective theory describing fermions at finite density is Landau's Fermi liquid theory. The theory is basically a free fixed point under the renormalization group flow toward the Fermi surface. The experimental observation of exotic "non-Fermi liquid" phases of matter has triggered enormous interest. Their theoretical description is hard due to the lack of Lorentz symmetry and the ubiquity of strong coupling. Thus, any new fermionic system is interesting if it can be studied in a controlled fashion. In this talk, I describe my recent research that focused on finding such systems in the controlled "laboratory" of the AdS/CFT correspondence. I describe various aspects of holographic fermions along with some of the motivations and challenges in the field of "AdS/CMT".

DESCRIPTION:Strongly interacting fermions at finite density are infamously hard to treat. Gauge/gravity duality gives a way of studying them in a controlled environment. For such studies to be reliable it is important that the models are eventually embedded in M-theory (or string theory). In this talk I will describe how to look for some of the most basic features of fermionic finite-density states in M-theory, such as the occurrence of Fermi surfaces, and describe the wider implications of our recent intriguing results on these objects.

SUMMARY:Physics Colloquium, "Strong-Arming Electron Spin Dynamics" (Jason Petta)
DESCRIPTION:Over ten years ago, Daniel Loss and David DiVincenzo proposed using the spin of a single electron as a quantum bit. At the time of the proposal, it was not possible to trap a single electron in a device and measure its spin, let alone demonstrate control of quantum coherence. In this talk I will describe recent progress in the field, focusing on two new methods for single spin control that have been developed by my group at Princeton. The first method is based on quantum interference and implements spin-interferometry on a chip. The second method utilizes the strong spin-orbit coupling of InAs. By shifting the orbital position of the electronic wavefunction at GHz frequencies, we can control the orientation of a single electron spin and measure the full g-tensor, which exhibits a large anisotropy due to spin-orbit interactions. Both methods for single spin control are orders of magnitude faster than conventional electron spin resonance and allow investigations of single spin coherence in the presence of fluctuating nuclear and spin-orbit fields.

DESCRIPTION:I will discuss the chiral phase transition in a magnetic field at finite temperature and chemical potential within the Sakai-Sugimoto model, a holographic top-down approach to (large-N_c) QCD. For small temperatures the addition of a magnetic field decreases the critical chemical potential for chiral symmetry restoration. This is in apparent contrast to the familiar phenomenon of magnetic catalysis, according to which the magnetic field favors the chirally broken phase. I will point out the physical mechanism behind this ``inverse magnetic catalysis'' and discuss extensions of the phase diagram by including baryonic matter.

SUMMARY:High Energy Theory Seminar, "Scattering Amplitudes and Wilson Loops in Twistor Space" (David Skinner, Perimeter Institute)
DESCRIPTION:Over the past few years, a remarkable duality between planar scattering amplitudes and null polygonal Wilson Loops has emerged in maximally supersymmetric Yang-Mills theory. The duality is now known to hold for arbitrary external helicities and to all orders in the 't Hooft coupling. I will review our understanding of this duality from the point of view of the twistor formulation of the theory. At tree level, the scattering amplitudes are powerfully constrained by an infinite dimensional Yangian symmetry. I will also argue that, properly understood, a large part of this symmetry extends to loop amplitudes.

DESCRIPTION:After decades of preparation, the experiments at the Large Hadron Collider (LHC)are taking the first steps toward resolving many long-standing puzzles about fundamentalphysics at the weak scale. There were high expectations for early discovery of Supersymmetry (SUSY) atthe beginning of the LHC search program. This talk summarizes the current experimental status and strategies used by the CMS Collaboration in the search for SUSY involving jets and missing energy in fully hadronic and leptonic final states. SUSY mass scales in the TeV range are excluded by these preliminary results. This poses the questions: Is SUSY still alive? And is it still accessible within the LHC reach for 7 TeV pp collisions?

DESCRIPTION:The collective behavior of a many-body system near a continuous phase transition is insensitive to the details of its microscopic physics. Characteristic features near the phase transition, called critical phenomena, are that the thermodynamic observables follow generalized scaling laws. In this talk, I will discuss the observation of scale invariance and universality in ultracold atomic gases based on direct in situ imaging. Our observation points toward a growing density-density correlations in the critical regime and raises new perspectives to explore universal quantum critical dynamics.

SUMMARY:High Energy Theory Seminar, "Carving Out the Space of 4D CFTs" (David Simmons-Duffin, Harvard University)
DESCRIPTION:We introduce a new numerical algorithm based on semidefinite programming to efficiently compute bounds on operator dimensions, central charges, and OPE coefficients in 4D conformal and N=1 superconformal field theories. Using our algorithm, we dramatically improve previous bounds on a number of CFT quantities, particularly for theories with global symmetries. In the case of SO(4) or SU(2) symmetry, our bounds severely constrain models of conformal technicolor. In N=1 superconformal theories, we place strong bounds on dim(Phi*Phi), where Phi is a chiral operator. These bounds asymptote to the line dim(Phi*Phi) <= 2 dim(Phi) near dim(Phi) ~ 1, forbidding positive anomalous dimensions in this region. We also place novel upper and lower bounds on OPE coefficients of protected operators in the Phi x Phi OPE. Finally, we find examples of lower bounds on central charges and flavor current two-point functions that scale with the size of global symmetry representations. In the case of N=1 theories with an SU(N) flavor symmetry, our bounds on current two-point functions lie within an O(1) factor of the values realized in supersymmetric QCD in the conformal window.

DESCRIPTION:I will discuss three ways in which (the string landscape and) eternal inflation is fun: (1) because it motivates revisiting some beautiful, classic calculations; (2) because its global description requires asking novel questions with possible broad ramifications; and (3) because it leads to experimental predictions.

SUMMARY:High Energy Theory Seminar, "A Natural Language for AdS/CFT Correlators and the Holographic S-Matrix" (Jared Kaplan, SLAC, Stanford University)
DESCRIPTION:We provide dramatic evidence that `Mellin space' is the natural home for correlation functions in CFTs with weakly coupled bulk duals. In Mellin space, CFT correlators have poles corresponding to an OPE decomposition into `left' and `right' sub-correlators, in direct analogy with the factorization channels of scattering amplitudes. In the regime where these correlators can be computed by tree level Witten diagrams in AdS, we derive an explicit formula for the residues of Mellin amplitudes at the corresponding factorization poles, and we use the conformal Casimir to show that these amplitudes obey algebraic finite difference equations. By analyzing the recursive structure of our factorization formula we obtain simple diagrammatic rules for the construction of Mellin amplitudes corresponding to tree-level Witten diagrams in any bulk scalar theory. We prove the diagrammatic rules using our finite difference equations. Finally, we show that our factorization formula and our diagrammatic rules morph into the flat space S-Matrix of the bulk theory, reproducing the usual Feynman rules, when we take the flat space limit of AdS/CFT. Throughout we emphasize a deep analogy with the properties of flat space scattering amplitudes in momentum space, which suggests that the Mellin amplitude may provide a holographic definition of the flat space S-Matrix.

SUMMARY:High Energy Physcis Seminar, "Recent results from the Tokai-to-Kamioka (T2K) Experiment" (Hiro Tanaka, University of British Columbia)
DESCRIPTION:I will report on recent results from the Tokai-to-Kamioka (T2K) experiment, which aims to make high sensitivity and precise studies of neutrino oscillation using an intense off-axis muon neutrino beam produced by the Japan Proton Accelerator Complex (J-PARC) and directed towards the Super Kamiokande (SK) detector 295 km away. By searching for the transition of muon neutrinos to electron neutrinos at SK, the experiment will extend the sensitivity to the yet-unobserved mixing parameter theta_13, a necessary ingredient for CP violation in the lepton sector. The deficit of muon neutrinos resulting from muon neutrino to tau neutrino oscillation will allow T2K to make precise measurements of theta_23 and Delta m^2_32, two other fundamental parameters of the lepton mixing matrix that will shed light on its structure, in particular the apparently maximal mixing suggested by current measurements. The reported results are based on data taken in 2010 and 2011 using 1.43x10^{20} protons-on-target.

SUMMARY:High Energy Theory Seminar, "Constraints on String Cosmology" (Callum Quigley, University of Chicago)
DESCRIPTION:String theory contains sources like orientifold planes that support higher derivative interactions. These interactions make possible static flux compactifications which are forbidden in supergravity. They can also lead to violations of the strong energy condition (SEC) which is needed for an accelerating universe. We examine how large a violation is possible in the context of the heterotic string compactified to four dimensions. We find that de Sitter solutions are still not possible but that classically forbidden anti-de Sitter solutions are possible.

DESCRIPTION:2011 has been the year when the Large Hadron Collider (LHC) became the world's leading experimental facility in the area of the fundamental particle interactions. The amount of data available for analysis is increasing exponentially. The search for the Higgs boson is entering its final phase and it is very likely that we will know for sure if it exists within a year or two. Results from the summer conference season look intriguing. The Atlas and CMS experiments exclude a wide range of possible Higgs masses, finding an excess at low mass, the favored mass region for the standard model Higgs. I will present results of the Higgs search at CMS concentrating on the WW leptonic final state - one of the most sensitive channels in the search for the Higgs.

SUMMARY:Physics Colloquium, "Entanglement and Quantum Algorithms with Superconducting Circuits" (Robert Schoelkopf, Yale University)
DESCRIPTION:By using the unique properties of quantum physics, such as entanglement and superposition, quantum computers are predicted to be vastly more powerful than their classical counterparts for certain tasks. While some technologies, such as NMR and trapped ions, have succeeded in making and manipulating a handful of quantum bits (qubits), they look quite different from a conventional computer, and there are many obstacles to building large-scale processors. At Yale, we use superconducting circuits to make macroscopic, solid-state qubits which are controlled and measured entirely by a sequence of electronic pulses on wires. These devices have advanced to the point where we can generate and detect highly-entangled states, and perform universal quantum gates. I will describe recent experiments showing the operation of Grovers search algorithm, and measurements of the violation of a Mermin inequality for a three-qubit entangled GHZ state.

SUMMARY:High Energy Theory Seminar, "Bootstrapping the Three-loop Hexagon" (Lance Dixon, SLAC, Stanford University)
DESCRIPTION:I discuss how to combine the physical constraints, in particular the operator product expansion for Wilson loops, with the technical power of the "symbol" of pure transcendental functions. The combination can be used to evaluate the (symbol for the) Wilson loop corresponding to the scattering amplitude for six (MHV) gluons in planar N=4 super-Yang-Mills theory through three loops, for general kinematics, up to a few constants.The multi-Regge limit of high-energy scattering can also be extracted easily from the symbol. In this limit the full functional dependence is known, up to a few constants. The results are consistent with earlier predictions, but also provided new, subleading and subsubleading logarithmicinformation. No loop integrands or loop integrals are required in thisapproach.

SUMMARY:Physics Colloquium, "On the Verge of Mechanical Instability" (Tom Lubensky, University of Pennsylvania)
DESCRIPTION:The mechanical stability of bridges, buildings, and other architectural wonders is of critical importance to us all. In 1864, James Clerk Maxwell formulated a theory for the stability of frames composed of straight struts, capable of supporting tension and compression, connected at points of contact. Of particular interest are isostatic systems that have just enough struts to ensure mechanical stability. Maxwell's ideas have found applications in many fields from civil engineering to biophysics. This talk will present an overview of condensed-matter systems from network glasses to jammed solids to networks of semi-flexible polymers for which Maxwell's ideas have provided fruitful insight.

SUMMARY:High Energy Theory Seminar, "The Harmony of Superstring Disk Amplitudes" (Oliver Schlotterer, Max Planck Institut fuer Gravitationsphysik - Albert Einstein Institut Potsdam)
DESCRIPTION:I will present the open string tree level amplitude of massless states to any number of external legs. It turns out that the kinematic factor of disk amplitudes is entirely captured by the underlying SYM field theory, i.e. that all the dependence on polarization vectors enters through color ordered SYM amplitudes. Moreover, the structure of the N point string theory amplitude exploits the minimal basis of (N-3)! SYM subamplitudes and adjoins a dual basis of (N-3)! hypergeometric functions encoding the alpha' corrections. These patterns within disk amplitudes exhibit rich implications from and to field theory. The pure spinor formalism is the crucial tool to identify SYM amplitudes within the string computation. That is why I introduce a compact representation for N point SYM amplitudes in pure spinor superspace. It reflects the decomposition into cubic diagrams a la Bern, Carrasco, Johansson and generalizes Berends Giele recursion relations.

I will also describe a class of non-local higher-spin Lagrangian couplings that are generically required by the Noether procedure starting from four-points. The construction clarifies the origin of old problems for these systems and links String Theory to some aspects of Field Theory that go beyond its conventional low energy limit. I will finally discuss how the extension of these results to (A)dS brings about the emergence of minimal-like couplings from higher-derivative ones.

SUMMARY:High Energy Theory Seminar, "Exact One-loop Strong Coupling Results for String Spectrum in AdS4 x CP3 Versus All-Loop Bethe Ansatz" (Andrew Zayakin, LMU, Garching)
DESCRIPTION:A non-trivial test of the string vs. integrability correspondence is suggested: exact equivalence is established between strings in AdS4 x CP3 and the Gromov-Vieira all-loop integrable chain. To do that, the complete one- and two-magnon sector of each respective theory are calculated. In the single-magnon sector a direct perturbative one-loop calculation proves the validity of the dispersion law coming from the Bethe Ansatz, rather than of the one coming from the semiclassical analysis. In the two-magnon sector the full spectrum of the finite-size corrections has been calculated on the string side by us for the first time, that proves to be identical to the integrable chain spectrum. These results are interpreted by us as a confirmation of the exactness of the conjectured Gromov-Vieira Bethe Ansatz.

SUMMARY:PCTS Program, "Exact Methods in Gauge/String Theories"
DESCRIPTION:The program focuses on a wide range of exact methods which have been developed over the last few years in the study of the non-perturbative dynamics of gauge/string theories. The keywords include localization techniques, matrix models and quantum integrable systems. These methods have already led to a wealth of important results, such as the exact computation of partition functions, the analysis of vacua of supersymmetric gauge theories, several precise tests of the AdS/CFT correspondence, and new non-perturbative dualities between gauge theories in various dimensions.The main purpose of the workshop is to gather leading researchers in these fields and overview the recent achievements. The speakers are chosen from rather broad areas, and we hope that their confrontation will stimulate new ideas and perspectives in these fields.

DESCRIPTION:In this talk I will discuss recent work constructing heterotic standard models by compactifying on smooth Calabi-Yau three-folds in the presence of purely Abelian internal gauge fields. The simple construction of these models allows for a large-scale, algorithmic approach to heterotic string phenomenology. In particular, a systematic search over complete intersection Calabi-Yau manifolds with less than six Kahler parameters has lead to over 1000 such models with exact SM spectra. In addition, the presence of additional global U(1) symmetries, leads to a rich phenomenological structure and places constraints on Yukawa couplings, R-parity violation, proton stability and neutrino masses.

SUMMARY:High Energy Theory Informal Seminar, "Instantons and Semi-Realistic Gauge Theories in Type II / F-theory and Their Duals" (Jim Halverson, University of Pennsylvania)
DESCRIPTION:Instantons in string theory can generate superpotential corrections useful for moduli stabilization or the existence of phenomenologically relevant couplings. In this talk, I will consider these issues from three points of view. First, I will present systematic "bottom-up" work on a class of MSSM-like gauge theories with anomalous U(1)'s (from IIa intersecting branes, e.g.). I will briefly discuss the importance of instantons for couplings in these theories. Instead the focus will mostly be on constraints on chiral matter necessary for string consistency, including the structure of matter beyond the MSSM "preferred" by these constraints. Next, I will discuss the computation and physics of instanton corrections in F-theory. Utilizing heterotic / F-theory duality, I will draw general conclusions about the moduli-dependent (Pfaffian) prefactor, including connections to the 7-brane gauge theory, and will also discuss some explicit examples. Finally, if time permits, I will briefly discuss how the systematic consideration of instanton effects leads one to the study of diophantine equations and will generalize the importance of diophantines to any physical effect defining a recursive set. I will argue that this gives rise to an issue of computability in the landscape by relation to Hilbert's tenth problem.

SUMMARY:Informal High Energy Theory Seminar, "Hunting De Sitter Holography from the Bottom Up" (Matthew Baumgart, Johns Hopkins University)
DESCRIPTION:The holographic RG of Anti-De Sitter gives a powerful clue about theunderlying AdS/CFT correspondence.The question is whether similar hints can be found for the heretoforeelusive holographic dual of De Sitter.The framework of stochastic inflation uses a nonperturbative insightin order to tame bad behavior in theperturbation series at late times. Recasting this as a "resummationof time", we wish understand whetherthe distributions that result can be thought of as an attractive UVfixed point of a theory living on a spacelikeslice of DS. I will discuss our rederivation of stochastic inflationin terms of wavefunctionals, the straightforwardway one can implement corrections to the leading approximations, andthe robustness of the late-time equilibriumto perturbations.

SUMMARY:Physics Group Meeting, "Multi-Lepton Signals of the Higgs Boson" (Nathaniel Craig, IAS)
DESCRIPTION:I'll evaluate the possibility of searching for the Higgs boson in channels with multiple non-resonant leptons in light of recent advances in multi-lepton search techniques at the LHC. The total multi-lepton Higgs signal exceeds the four lepton gold-plated resonant mode, but is spread over many channels with same-sign di-lepton, tri-lepton, and four lepton final states. While any individual channel alone is not significant, the exclusive combination across multiple channels provides a sensitivity competitive with other discovery level searches for the Higgs boson. I'll also discuss more generally the most recent multi-lepton search results from ATLAS and CMS from a theorist's perspective.

SUMMARY:High Energy Theory Seminar, "Locally Localized Gravity in String Theory" (John Estes, University of Leuven, Belgium)
DESCRIPTION:Localized gravity is the idea of obtaining an effective 4D gravitational theory from higher-dimensions without compactification. This is done by localizing a set of gravitational degrees of freedom along a 4D submanifold (brane-world), while the coupling of the brane-world to the remaining gravitational degrees of freedom is suppressed. A realization in classical gravity was given by A. Karch and L. Randall by inserting an AdS_4 brane-source into AdS_5. I will discuss an embedding of this scenario into string theory by insertingD5- and NS5-branes into the near horizon geometry of D3-branes. In particular, the backreacted solutions are presented and analyzed. Novel AdS_4 geometries relevant to gravity localization are found. I will also discuss their relation to 3D SCFTs.

SUMMARY:High Energy Theory Seminar, "ABJM Theory as a Fermi Gas" (Pavel Putrov, University of Geneva)
DESCRIPTION:The partition function on the three-sphere of many supersymmetric Chern-Simons-matter theories reduces, by localization, to a matrix model. In this talk I will describe a new method to study these models in the M-theory limit, but at all orders in the 1/N expansion. The method is based on reformulating the matrix model as the partition function of a Fermi gas. This new approach leads to a completely elementary derivation of the N^{3/2} behavior for ABJM theory and other quiver Chern-Simons-matter theories. In addition, the full series of 1/N corrections to the original matrix integral can be simply determined by a next-to-leading calculation in the semiclassical expansion of the quantum gas.

SUMMARY:Informal High Energy Theory Seminar, "From Trees to Two Loops by Maximal Unitarity" (Kasper Larsen, CEA, France)
DESCRIPTION:In this talk we take the first steps towards a new framework for computing two-loop amplitudes, based on unitarity rather than Feynman diagrams. In this approach, the two-loop amplitude is first expanded in a basis of integrals. The expansion coefficients are then determined by applying generalized unitarity cuts. We find explicit formulas for the integral coefficients as products of tree level amplitudes integrated over specific contours in the complex plane, thus allowing to construct the two-loop amplitude from appropriately defined tree amplitudes. The validity of this method extends to all 4-dimensional gauge theories, in particular QCD. This approach is suited for obtaining analytical expressions as well as for numerical implementations.

SUMMARY:Physics Colloquium, "Taking a 'nu' Look : Studying Low Energy Solar and Terrestrial Neutrinos with Borexino" (Alex Wright, Princeton University)
DESCRIPTION:Solar neutrino experiments have taught us a great deal about neutrinos, neutrino oscillations, and the nuclear fusion reactions that power the sun. The Borexino experiment, in which the Princeton particle astrophysics group plays a leading role, has made important new solar neutrino measurements by extending neutrino spectroscopy to very low energies. In this talk I will review what we have learned (and are still learning!) about solar neutrinos and the Sun. I will also describe our first measurement of the flux of terrestrially produced "geo-neutrinos" and how this and similar measurements can allow us to study the chemical composition of the Earth's interior and to better understand the planet's thermal history.

SUMMARY:Physics Colloquium, "Statistical Mechanics of the Genetic Code: A Glimpse of Early Life?" (Nigel Goldenfeld)
DESCRIPTION:Relics of early life, preceding even the last universal common ancestor of all life on Earth, are present in the structure of the modern day canonical genetic code. In this talk, I will draw attention to these relics, and discuss their interpretation from the perspective of the dynamical system that is evolution. I will argue that this viewpoint, and the quantitative, statistical dynamical calculations that it entails, suggest a natural scenario in which evolution exhibits three distinct dynamical regimes, differentiated respectively by the way in which information flow, genetic novelty and complexity emerge. Possible observational signatures of these predictions are discussed.

At present solution is being carried out in a weak coupling expansion.

DESCRIPTION:One of the challenges of 21st century particle physics is a deficit of observations to constrain/shape hypotheses for what may be "the"Theory Of Everything, or at least a next stage in our development of such. I present one of the searches motivated by cosmological evidence for particulate dark matter, which aims to unearth signals in the wide-coverage but xperimentally difficult all-hadronic jets and missing transverse momentum channel. Along the way, I hope to give you a flavor of how analysis challenges in these (still) start-up days of the experiment were discovered and met, but also some thoughts on challenges we might expect in the future of dark matter searches and ways to approach them.

SUMMARY:High Energy Theory Seminar, "Connecting Strings to Things" (Jonathan Heckman, IAS)
DESCRIPTION:In this talk I describe some of the recent progress made in embedding the Standard Model of particle physics in a theory of open strings. In the first half of the talk, I focus on a particular limit where 4D gravity is decoupled, reviewing some of the ingredients which go into the construction of stringy Standard Models which contain theoretically desirable features such as supersymmetric gauge coupling unification and viable quark and lepton masses and mixing angles. In the second half of the talk I discuss a recent proposal for reintroducing some features of 4D gravity using a symmetry preserving regulator of the 4D spacetime.Concentrating on a simplified situation with additional supersymmetry, I describe a conjectured reformulation of the 4D effective theory as a large N matrix model, in which gravity and the continuum spacetime both emerge in a large N double scaling limit. I conclude with some potential avenues of future investigation.

SUMMARY:High Energy Theory Seminar, "The Large N Limit of Tensor Models" (Razvan Gurau, Perimeter Institute)
DESCRIPTION:Matrix models yield a theory of random two dimensional surfaces. They support a 1/N expansion dominated by planar graphs (corresponding to planar surfaces) and undergo a phase transition to a continuum theory. In higher dimensions matrix models generalize to tensor models. In the absence of a viable 1/N expansion tensor models have proved less successful in providing a theory of random higher dimensional spaces. I will show that models for a non symmetric complex tensor admit a 1/N expansion dominated by graphs of spherical topology in arbitrary dimensions and undergo a phase transition to a continuum theory.

DESCRIPTION:In biological systems, there are striking examples where complicated structures (i.e., the bacterial ribosome) can spontaneously assemble, driven by specific interactions between the components. But how can systems be designed to have this property? Recent technological advances have created the opportunity for making technologically relevant systems that self assemble, by e.g. coating colloidal particles with DNA. We will discuss how self assembly works in this system, through theory, numerical simulation and experiment -- and start to speculate as to whether resulting principles might be useful for unravelling the rules of biological self-assembly.

SUMMARY:High Energy Theory Seminar, "Loop Quantum Gravity: Recent Results and Open Problems" (Carlo Rovelli, Centre de Physique Théorique de Luminy, Aix-Marseille University, France)
DESCRIPTION:The loop approach to quantum gravity has developed considerably during thelast few years, especially in its covariant ('spinfoam') version. Ipresent thecurrent definition of the theory and the results that have beenproven. I discusswhat I think is still missing towards of the goal of defining aconsistent tentativequantum field theory genuinely background independent and having generalrelativity as classical limit.
