## Upcoming Events

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…

## Past Events

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

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.

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.
