Speaker: Marek Liška (DIAS)
Abstract: Since the seminal work of T. Jacobson, it has been known that thermodynamics of local causal horizons encodes equations governing gravitational dynamics. I discuss how this thermodynamic perspective can improve our understanding of gravity. I first argue that the classical dynamics implied by thermodynamics correspond to unimodular (Weyl transverse) gravity rather than to general relativity. In the second part of the talk, I then show how thermodynamics of local causal horizons may allow us to study the low energy quantum gravitational effects and discuss its implications in several different regimes.
