Entanglement islands and information recovery from near-extremal regular black holes
Ankit Anand, Kimet Jusufi, Amir A. Khodahami +1
We investigate the Page curve and information recovery in a near-extremal regular black hole inspired by T-duality, in which the central singularity is resolved by a minimal length…
Unified dark sector and Hubble-tension alleviation in scalar-vector-tensor gravity
Kimet Jusufi, Amir A. Khodahami, Ahmad Sheykhi +2
We investigate a scalar-vector-tensor theory in which matter is minimally coupled to a Jordan-frame metric , while a massive vector sector interacts with…
An Effective Framework for Entropy Modifications via Stochastic Metric Fluctuations
Amir A. Khodahami, Ahmad Sheykhi
Deviations from the area law of horizon entropy are often modeled phenomenologically through modified Friedmann equations in cosmology. In this work, we explore an effective stocha…
A revision to the QES prescription
Amir A. Khodahami, Azizollah Azizi
In this paper, we propose a revision to the Quantum Extremal Surface (QES) prescription, which plays a crucial role in describing the entanglement entropy of black holes. While der…
Holography and the Page curve of an evaporating black hole
Amir A. Khodahami, Azizollah Azizi
The Page curve exhibits a sharp peak at the Page time corresponding to a phase transition from an empty quantum extremal surface to a non-empty one. This study delves into the impa…
Replica wormhole and AMPS firewall
Amir A. Khodahami, Azizollah Azizi
We investigate the potential for generating an AMPS firewall from the replica wormhole topology, which describes the post-Page time spacetime in the evaporation process of a black…
