Physics Calendar

The Physics calendar contains High Energy Theory events hosted by the Institute for Advanced Study and Princeton University. A condensed version of the calendar is sent to the general Physics mailing list on Friday afternoons. Reminder emails are sent the morning of the event. If you are a local faculty member, postdoc or graduate student and would like to be added to the general Physics mailing list, please contact Lisa Fleischer, lisa@ias.edu

IAS CMP/QFT Group Meeting

Classifying 2D Gapped Phases on the Lattice, Up to Invertible Phases
Daniel Ranard
11:00am|Bloomberg Lecture Hall (IAS)

Abstract: We often say two gapped lattice Hamiltonians are in the same topological phase if they are connected by a path of gapped Hamiltonians. For 2D spin systems, it is conjectured that each phase is uniquely specified by the modular tensor...

IAS Phenomenology Lunch and Meet

Information Discussions on Phenomenology and New Theories beyond the Standard Model
12:30pm|Bloomberg Hall Biology Conference Room (1st Floor, Room 113)

This semester, we will be beginning a *very informal* get-together every Monday of people interested in/working on phenomenology and new theories beyond the standard model.  The idea is to discuss over lunch, perhaps meet up around 12.20, grab lunch...

Princeton University Gravity Initiative Seminar

Where is the Second Multi-Messenger Compact Object Merger? Insight from Observations of GRBs, Kilonovae and Afterglows
Jillian Chin Rastinejad
12:30pm|Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: With only one joint gravitational wave (GW)-electromagnetic (EM) detection to date, observations of the EM counterparts to neutron star mergers are a key path to probing the physics of these unique systems and predicting the behavior of...

Princeton University High Energy Theory Seminar

Revisiting the Gauss Law in M-theory
Vivek Saxena
2:30pm|Jadwin Hall, PCTS Room 407

Abstract:  In gauge theories with Chern-Simons interactions, the Gauss law -- the requirement that physical states be gauge invariant -- implies that the quantum wavefunction is naturally a section of a nontrivial line bundle over the space of...

Princeton University Gravity Initiative Seminar

Decay estimates for massless Vlasov fields on subextremal Kerr spacetimes
Leo Bigorgne
12:30pm|Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: We will present a commutation vector field approach for the solutions to the massless Vlasov equation on the exterior of a Schwarzschild spacetime, together with extensions to subextremal Kerr black holes. The approach satisfies two...
