Planar Black Holes in Holographic Axion Gravity: Islands, Page Times, and Scrambling Times
Seyed Ali Hosseini Mansoori, Orlando Luongo, Stefano Mancini +3
The present work investigates the entanglement entropies of the Hawking radiations, the Page times, and the scrambling times, for the eternal planar black holes in the holographic…
Hawking modes and the optimal disperser : Holographic lessons from the observer's causal-patch unitarity
Javad Koohbor, Mohammad Nouri-Zonoz, Alireza Tavanfar
Based on an observer-centric methodology, we pinpoint the basic origin of the spectral Planckianity of the asymptotic Hawking modes in the conventional treatments of the evaporatin…
Electron stars for holographic metallic criticality
Sean A. Hartnoll, Alireza Tavanfar
We refer to the ground state of a gravitating, charged ideal fluid of fermions held at a finite chemical potential as an `electron star'. In a holographic setting, electron stars a…
The Point of E_8 in F-theory GUTs
Jonathan J. Heckman, Alireza Tavanfar, Cumrun Vafa
We show that in F-theory GUTs, a natural explanation of flavor hierarchies in the quark and lepton sector requires a single point of E_8 enhancement in the internal geometry, from…
Cosmology of F-theory GUTs
Jonathan J. Heckman, Alireza Tavanfar, Cumrun Vafa
In this paper we study the interplay between the recently proposed F-theory GUTs and cosmology. Despite the fact that the parameter range for F-theory GUT models is very narrow, we…
Critical formation of trapped surfaces in the collision of gravitational shock waves
Luis Alvarez-Gaume, Cesar Gomez, Agustin Sabio Vera +2
We study the formation of marginally trapped surfaces in the head-on collision of two shock waves both in anti-de Sitter and Minkowski space-time in various dimensions as a functio…
