Title: Exploring Gravitational Entropy

Speaker: Dr. Ronak Soni, DAMTP, Cambridge University

Abstract: One of the most striking facts about gravity is that it tells us that black holes have a large entropy that scales inversely with the Newton's constant. Even more striking is that the theory of gravity does not contain the microstates that this entropy counts. In this talk, I want to describe some ways in which the community has explored this entropy, like the fact that this gravitational entropy seamlessly interconverts with quantum mechanical entanglement entropy. I will also outline some exact and approximate ways of thinking about this entropy and mention some open questions entailed by these.
