BLHW03 - Bridges between holographic quantum information and quantum gravity

In this talk, I will discuss the gravitational edge mode of the N=1 Jackiw-Teitelboim (JT) supergravity. First, I will review the gravitational edge mode from the bosonic JT gravity. I will discuss the issues related to dilaton and PSL gauging in the derivation of the Schwarzian action. I will revisit the derivation of Schwarzian action for the edge mode by using the inversion formula of Schwarzian derivative. I will explain how to obtain N=1 super-Schwarzian action. I will also discuss the relation between osp(2,1) gauging and isometry.
