IAS Quantum Aspects of Black Holes Group Meeting

Abstract: Abstract: In this talk, I will review the underlying algebraic structure of de Sitter quasinormal modes (QNMs), and the relation between QNMs and one-loop quantum corrections to dS entropy. I will explain how this picture extends to Anti-de Sitter space and more general black hole backgrounds. Depending on time, I will also talk about some ongoing work on higher loop corrections to dS entropy.

The talk will be based on:
