Upcoming HET and HEE Seminars



High Energy Theory Seminar: Comments on the density matrix of the universe in two dimensional quantum cosmology

Andreas Blommaert (Institute for Advanced Study)
- David Rittenhouse Laboratory, 3W2

I discuss work in progress on obtaining a reasonable density matrix of the universe in two dimensional quantum cosmology. I will do so by comparing aspects of the Hilbert space of closed universes in JT gravity…



High Energy Theory Seminar: Real-Time Path Integrals, Caustics and Interference

Job Felbrugge (University of Edinburgh)
- David Rittenhouse Laboratory, 3W2

Interference is one of the most universal phenomena in nature, as exemplified by the real-time Feynman path integral. Despite the ubiquity of interference patterns, their evaluation has often proven challenging.…



High Energy Theory Seminar: "TBA"

Yue-Zhou Li (Princeton)
- David Rittenhouse Laboratory, 3W2



Experimental Particle Physics Seminar: Studying the Higgs boson at the LHC and beyond

Liza Brost (BNL)
- David Rittenhouse Laboratory, 3W2

Past HET and HEE Seminars



Experimental Particle Physics Seminar: Real-time Anomaly Detection at the CMS Experiment

Isobel Ojalvo (Princeton)
- David Rittenhouse Laboratory, 3W2



High Energy Theory Seminar: CMB limits on decaying dark matter: going beyond the ionization threshold

Wenzer Qin (NYU)
- David Rittenhouse Laboratory, 3W2

The temperature and polarization anisotropies of the cosmic microwave background (CMB) have been used to set constraints on decaying dark matter models down to keV masses. In this talk, I will discuss recent work to…



High Energy Theory Seminar: Holography and symmetries of supersymmetric Chern-Simons theories

Oren Bergman (Israel Institute of Technology)
- David Rittenhouse Laboratory, 3W2

I will derive the symmetry theories of the 3d N=6 and N=5 supersymmetric Chern-Simons-Matter theories from holography.

Focusing on a specific variant of the N=5 theory that has a non-abelian…



High Energy Theory Seminar: Gravitational-wave memory effects from binary-black-hole mergers

David Nichols (University of Virginia)
- David Rittenhouse Laboratory, 3W2

The LIGO-Virgo-KAGRA Collaboration has detected nearly one hundred black-hole mergers in its first three observing runs and is finding several candidate mergers every week during its ongoing fourth run. These mergers…



High Energy Theory Seminar: Averaged null energy and the renormalization group

Tom Hartman (Cornell University)
- David Rittenhouse Laboratory, 3W2

The averaged null energy condition, or ANEC, is a fundamental bound on negative energy in quantum field theory. It has applications ranging from black holes to quantum information to the 3D Ising model,…
