Firewalls from wormholes in higher genus

Abstract

An old black hole can tunnel into a white hole/ firewall by emitting large baby universes. This phenomenon was investigated in Jackiw-Teitelboim (JT) gravity for genus one. In this paper, the focus is on higher genus corresponding to emitting more than one baby universe (n > 1). The probability of encountering a firewall or tunneling into a white hole after emitting n baby universes is proportional to e-2nS(E)e4 π E(n-1)E2n2-n-9/2t4n2-2n-5, where t is the age of the black hole, and S and E represent the entropy and energy of the black hole, respectively.
