High Energy Theory Seminar
“Continuous 2-group symmetry of 6d N=(1,0) LST and T-dualities”

Location: Bloomberg Lecture Hall
Time: 1:45 PM
Speaker(s): Kantaro Ohmori, Member, School of Natural Sciences, IAS

Description: It is recently recognized that the global symmetry of a theory can be a nontrivial mixture of 0-form and 1-form global symmetries, called 2-group symmetry. A place where 2-group symmetry ubiquitously exists is 6d N=(1,0) little string theories. In this talk I will describe some formulas computing structure constants of the continuous part of the 2-group symmetry of 6d LSTs, and will demonstrate in examples the fact that the structure constants beautifully matches among the LSTs that are expected to be T-dual to each other.

High Energy Theory Seminar
“Higher algebraic Structures in SUSY QFT”

Location: Jadwin Hall, PCTS Seminar Room
Time: 2:30 PM
Speaker(s): Tudor Dimofte, University of California, Davis

Description: In a TQFT of homological type, such as arises from the topological twist of a supersymmetric theory, it is well known that the local operators form an algebra, associative in dimension d >= 1 and commutative in d >= 2. The product comes from collision of operators. I will explain how modern mathematical ideas in TQFT (in particular, the notion of $E_d$ algebras) lead to the existence of a *secondary* product in any dimension d, which acts as a generalized Lie bracket, and has a simple physical definition in terms of topological descent. In d=2, the secondary product is familiar as part of the L-infinity structure of local operators; in d >= 3 it has been relatively unexplored. I will use the secondary product to give a topological interpretation of the physical idea that "Omega background leads to quantization." Time permitting, I will explain some generalizations of the secondary product to line and surface operators, with interesting applications in d=3 and d=4. (Based on joint work with C. Beem, D. Ben-Zvi, M. Bullimore, A. Neitzke.)

Pheno & Vino Seminar
“Detecting Dark Matter from Supernovae”

Time: 4:00 PM
Speaker(s): Gustavo Markes Tavares, Stanford University

Description: The central region of Supernovae are one of the hottest and densest regions in the Universe. Due to the high temperatures, particles with sub-GeV masses can be copiously produced if they have non-negligible couplings to the Standard Model. If dark matter has sub-GeV mass it will be produced in the hot Supernovae core and it will have sufficiently large momenta to be detectable in direct detection experiments. In this talk I discuss the sensitivity of current and future Xenon based direct detection experiments to a simplified model of dark matter which interacts with the Standard Model via the dark photon portal.

Princeton University Department of Physics Donald R. Hamilton Colloquium Series
“Probabilistic Approach to Critical Phenomena in Statistical Physics”

Time: 4:00 PM
Speaker(s): Hugo Duminil Copin, IHES

Description: The talk will present some of the recent progress in mathematical studies of critical phenomena of classical statistical mechanical systems. Through the relation of quantum systems to classical systems in d+1 dimensions, some of these new results also yield new understanding of the ground states of a class of quantum spin chains with a projection based Hamiltonian.

PCTS Workshop
“Novel Ideas for Dark Matter”

Location: Jadwin Hall, Fourth Floor, Room 407, PCTS Seminar Room
Time: 8:30 AM

Description: Dark matter research is undergoing a paradigm shift. Over the last few years, many novel theories have been proposed that challenge the standard assumptions made about dark matter. At the same time, new observations and simulation results are providing valuable clues regarding the most fruitful directions moving forward.

The “Novel Ideas for Dark Matter 2019” workshop at Princeton University attempts to bridge the gap between communities working on non-standard solutions to the dark matter problem. Plenary talks on theory, observations and simulations will be structured into a three day schedule that will provide a broad overview of research avenues of this type. The workshop aims to promote conversations between research communities with ample time for open discussion.

Organizing committee:
Oren Slone - oslone@princeton.edu
Mariangela Lisanti - mlistanti@princeton.edu
Tomer Volansky - tomerv@post.tau.ac.il
