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...

Institute for Advanced Study / Princeton University Joint Astrophysics Colloquium

Supercomputer Simulations of the Universe
Volker Springel
11:00am|Peyton Hall Auditorium

Numerical simulations of cosmic structure formation have become a powerful tool in astrophysics. Starting right after the Big Bang, they predict the dark matter backbone of the cosmic web far into the non-linear regime and follow complex galaxy...
