SUMMARY:Gravitational edge mode for 2D gravity - Junggi Yoon (Asia Pacific
  Center for Theoretical Physics)
DTSTART:20231127T113000Z
DTEND:20231127T123000Z
UID:TALK203680@talks.cam.ac.uk
DESCRIPTION:In this talk\, I will discuss the gravitational edge mode of t
 he N=1 Jackiw-Teitelboim (JT) supergravity. First\, I will review the grav
 itational edge mode from the bosonic JT gravity. I will discuss the issues
  related to dilaton and PSL(2\,R) gauging in the derivation of the Schwarz
 ian action. I will revisit the derivation of Schwarzian action for the edg
 e mode by using the inversion formula of Schwarzian derivative. I will exp
 lain how to obtain N=1 super-Schwarzian action. I will also discuss the re
 lation between osp(2\,1) gauging and isometry.
