Building on earlier work with Eberhardt and Gaberdiel, where we identified the dual to the free symmetric orbifold CFT as string theory on AdS_3xS_3xT^4 with one unit of NS-NS flux, we consider…

One hundred years after Heisenberg’s Uncertainty Principle, the question of how to make simultaneous measurements of noncommuting observables lingers.  I will survey one hundred years of…

Correlators in field theories at finite temperatures have singularities on the light cone. Are there any other singularities?

Emil Martinec

Three separate worldsheet computations illustrate string theoretic aspects of AdS3/CFT2 duality: (1) Hawking radiation of winding strings; (2) BPS fivebrane “stars” near the black hole threshold;…

The integrable TT + \Lambda_2 deformation of a holographic CFT_2 contains universal dressed energy bands whose state count matches the refined Gibbons-Hawking entropy of dS_3, as predicted by…

I will discuss the various concepts of temperature that appear in the holographic description of de Sitter space using double-scaled SYK (DSSYK) as a motivating example.

We investigate new black hole solutions in AdS space that dominate the ensemble at high angular momentum. We conjecture that these black holes are the endpoint of the super radiant instability of…

In this talk, I will first describe on obtaining a microcanonical thermofield double state at fixed energy and angular momentum from the gravitational path integral.
