Random Matrix Spectroscopy and Quantum Gravity
Clifford Johnson, University of Southern California,

In order to fully interpret the meaning of random matrix model (RMM) formulations of JT gravity and related 2D gravity models, it is essential to have a fully non-perturbative formulation. Rather than supply an ensemble dual, as is so often stated (with puzzling consequences), a RMM is instead a natural Wignerian toolbox for understanding the properties of the 1D holographic dual, in particular the discrete black hole spectrum implied by the Bekenstein-Hawking entropy. With this perspective, black hole thermodynamics, as well as the emergence of wormholes, are simply understood. If time permits, new analytic results for the properties of the ground state distribution function will also be presented. It is a gravitational analogue of the Tracy-Widom distribution.

In person attendees (469 Lauritsen) must have a valid Caltech ID.
