Limits of JT gravity

Abstract: Jackiw—Teitelboim (JT) gravity is a model of two-dimensional dilaton gravity that has been central to many interesting developments (e.g., SYK model, random matrix models, island proposal) in the last couple of years. In this talk I will discuss various limits of JT gravity, including Newton—Cartan (non-relativistic) and Carrollian (ultra-relativistic) versions of two-dimensional dilaton gravity. After defining suitable boundary conditions, I will then discuss the issue of constructing boundary actions that capture the non-trivial dynamics at the boundary of these models.
