Schrödinger symmetry of Schwarzschild-(A)dS black hole mechanics

Autor: Ben Achour, Jibril, Livine, Etera R., Oriti, Daniele

We show that the dynamics of Schwarzschild-(A)dS black holes admit a symmetry under the 2d Schr\"{o}dinger group, whatever the sign or value of the cosmological constant. This is achieved by reformulating the spherically-symmetric reduction of genera

Hidden conformal symmetry on the black hole photon sphere

Autor: Bernard Raffaelli

Publikováno v: Journal of High Energy Physics

We consider a class of static and spherically symmetric black hole geometries endowed with a photon sphere. On the one hand, we show that close to the photon sphere, a massless scalar field theory exhibits a simple dynamical $SL(2,\mathbb{R})$ algebr

Multi-centered bubbling solutions are black hole microstate geometries that arise as smooth solutions of 5-dimensional $\mathcal{N}=2$ Supergravity. When these solutions reach the scaling limit, their resulting geometries develop an infinitely deep t

This article presents a new model-independent constraint for bouncing black hole geometries. Using the thin shell formalism, this constraint sets a bound on the minimal allowed radius of the time-like surface of the collapsing star at the bounce. It

The aim of this paper is to elucidate a close connection between the black hole area law and the infinite distance conjecture in the context of the swampland. We consider families of black hole geometries, parametrized by their event horizon areas or
