Christopher Dessert of Tufts University will be giving the LITP Monday Colloquium on October 19, 2026.
Event Type: Colloquia
I will discuss aspects of the duality between the two matrix models and 2D string theory at the self-dual radius. This duality doesn't require double scaling in the matrix integral, as opposed to the…
The Bekenstein-Hawking formula receives significant corrections for charged black holes near extremality. Using standard results in JT gravity, the correction term can semiclassically be expressed as…
The approach to a black hole singularity is described by an interior cosmological spacetime. I will explain how key geometric features of this interior spacetime are audible in the asymptotic, large…
Recent work has highlighted a subtle feature of large-N limits in holography: a sequence of pure microscopic states need not remain pure with respect to the emergent algebra of observables. In this…
Abstract: Supersymmetric black holes have zero temperature but their dependence on chemical potentials defines rather conventional thermodynamics. In anti-deSitter space, the phase diagram exhibits a…
Stanford University APPLIED PHYSICS/PHYSICS COLLOQUIUM Tuesday, February 22, 2022 3:30 p.m. on campus in Hewlett Teaching Center, Rm. 200 Light refreshments served in Varian lobby at 3:15 p.m. Please…
Abstract: The history of perturbative calculations in de Sitter space is littered with confusing and often contradictory results. The challenge is primarily the technical difficulty in performing loop…
Abstract: Several puzzles and issues in quantum gravity are related to the question of what type of high-energy information is actually available to low-energy observers. In this talk I will try to…
Abstract: A quantum system is said to be many-body localized (MBL) if it remains close to its initial state, i.e., it fails to thermalize. In 2016, I published a proof that certain one-dimensional…
