CPT Student Seminar: Entanglement Entropy and Perturbed Black Holes
26 October 2015 17:00 in OC218
The Ryu-Takayanagi hypothesis and its covariant generalization state that the entanglement entropy of a region in a CFT is given by the surface area of a minimal extremal surface in the holographic dual gravitational theory. But what is entanglement entropy? The first half of this presentation will be a gentle introduction to the notion of entanglement entropy as a measure of the amount of entanglement. The second half will be a not so gentle exploration of the entanglement structure of perturbed thermofield double states in 1+1 dimensions, via analysis of their holographic duals - perturbed BTZ black holes.

A gathering of mathematicians from the CPT group with physicists from IPPP, we meet to discuss our work in a relaxed and friendly environment.
