Holography in CGHS supergravity
Hamid Afshar, Narges Aghamir
TL;DR
This paper explores the holographic properties of 2D dilaton-supergravity in flat spacetime, revealing supersymmetric asymptotic symmetries and a super-warped Schwarzian boundary theory, along with black hole thermodynamics.
Contribution
It introduces a gauge theoretic BF formulation for 2D dilaton-supergravity, identifies supersymmetric warped Virasoro asymptotic symmetries, and derives the boundary super-warped Schwarzian action.
Findings
Asymptotic symmetries form a supersymmetric warped Virasoro algebra.
Boundary action is a super-warped Schwarzian theory.
Black hole thermodynamics are analyzed within this framework.
Abstract
We study holographic aspects of 2D dilaton-supergravity in flat space-time using gauge theoretic BF formulation. The asymptotic symmetries in Bondi gauge and at finite temperature span a supersymmetric extension of the warped Virasoro algebra at level zero. The boundary action is determined such that the bulk variational principle is ensured and turns out to be a super-warped Schwarzian theory at the vanishing level. We also study the thermodynamics of the black hole saddle in this model.
