    Pheno & Vino Seminar
    “New Direct-Detection Probes of sub-GeV Dark Matter”

    Location: Jadwin Hall, Room 303
    Time: 4:00 PM
    Speaker(s): Rouven Essig, Stony Brook University

    Description: Dark matter with MeV-to-GeV masses is a theoretically and phenomenologically interesting possibility.  In this talk, I will describe how direct-detection experiments can probe this largely unexplored mass range.  A particularly promising possibility is that dark matter scatters off electrons, causing ionization or excitation of atoms in a detector target material, which can lead to events containing one or more electrons or photons.  I will review how existing XENON10 data probes dark matter with masses as low as a few MeV, and present an improved constraint using recent XENON100 data.  After reviewing the challenges for xenon-based experiments to make further progress, I will discuss how experiments with different materials could significantly improve the sensitivity.  This includes upcoming experiments using semiconductors (e.g. SuperCDMS, DAMIC) as well as new dedicated experiments using scintillators and other materials.  I will focus on ideas that could be realized within the next five years, but also mention other efforts.  I will also present a few simple sub-GeV dark matter models, which provide concrete experimental targets, and contrast direct-detection probes with searches at colliders and fixed-target experiments.

    Special Condensed Matter Seminar

    Location: Jadwin Hall, PCTS Seminar Room - 407
    Time: 2:00 PM
    Speaker(s): Adam Nahum, MIT
    Note: Host: Professor David Huse

    Description: A quantum many-body system, prepared initially in a state with low entanglement, will entangle distant regions dynamically. How does this happen? I will discuss entanglement entropy growth for quantum systems subject to random unitary dynamics — i.e. Hamiltonian evolution with time-dependent noise, or a random quantum circuit. I will show how entanglement growth in this ‘noisy’ situation exhibits remarkable universal structure, which in 1D is related to the Kardar—Parisi—Zhang equation. I will argue that understanding this structure leads us to heuristic pictures for entanglement growth which may be useful for more general (non-noisy) dynamics.

    Hamilton Colloquium Series
    “The Dynamical Strong-field Regime of General Relativity”

    Location: Jadwin Hall, Room A10
    Time: 4:30 PM
    Speaker(s): Frans Pretorius, Princeton University

    Description: In this talk I will describe the recent detection of gravitational waves by the LIGO/Virgo collaboration. The main event heard, GW150914, is consistent with the emission of gravitational waves from the late inspiral, merger and ringdown of two heavy stellar mass black holes. Many aspects of this event are fortuitous and remarkable, and I will discuss what it has taught us about strong-field gravity, binary black hole populations in the universe, and what it implies we can further learn over the next few years once LIGO is upgraded to design sensitivity.

    Informal HET Seminar
    “Rethinking the Origin of Small Neutrino Masses”

    Location: Bloomberg Lecture Hall
    Time: 1:30 PM
    Speaker(s): Lena Funcke, Max Planck Institute for Physics and Ludwig Maximilian University of Munich

    Description: The observed small neutrino masses are one of the greatest mysteries in current theoretical particle physics. Many possible origins have been proposed so far, such as the see-saw mechanism, radiative corrections, or large extra dimensions. While all these models have been connected in some way to the Higgs condensate, we propose a substantially different mechanism based on nonperturbative gravity: assuming that gravity contains a topological theta-term analogous to the famous theta-term of QCD, we show that a neutrino condensate emerges and effectively generates the small neutrino masses. This neutrino mass generation mechanism implies numerous phenomenological consequences, such as the invalidity of the cosmological neutrino mass bound, enhanced neutrino-neutrino interactions, and neutrino decays.

    PCTS Workshop
    “Journey to the Center of the Bulk”

    Location: Jadwin Hall, PCTS Seminar Room, Fourth Floor, Room 407
    Time: 8:30 AM
    Note: FREE, but REQUIRED REGISTRATION is limited and available online at http://pcts.princeton.edu/pcts

    Description: This workshop will unify two broad topics of recent interest, brought together by the AdS/CFT correspondence: the construction of novel probes of spacetime dynamics in gravity and string theory, and non-perturbative methods for constraining the space of unitary CFTs and theories of AdS quantum gravity. Through the lens of quantum chaos, entanglement dynamics and the conformal bootstrap at large central charge, the workshop aims to illuminate the structure of holographic CFTs and the mechanism of emergence of classical geometry.
