Entanglement entropy and higher derivative Gravity

If you have a question about this talk, please contact Helvi Witek.

I will discuss the Maldacena-Lewkowycz derivation of the Ryu-Takayangi prescription for holographic entanglement entropy, and extend it to a more general class of theories of gravity in the bulk. This analysis results in a new Euclidean entropy functional, that generalises Wald’s entropy. In the Lorentzian, this functional is a natural extension of Wald’s black hole entropy to time dependent situations.
