Defects extremal surfaces and interface CFTs

Ankur Dey

The paper extends the defect extremal surface prescription to holographic interface CFTs, showing it matches lower-dimensional island formula results for entanglement entropy and c…

Kerr-de Sitter Black Holes: Quantum Aspects and Cosmic Censorship Conjecture

Ankit Anand, Ankur Dey

In this article, we test the validity of the weak cosmic censorship conjecture (wCCC) in the background of a quantum Kerr-de Sitter (qKdS) black hole, incorporating exact backreact…

Entanglement, defects, and on a black hole background

Ankur Dey

In this article, we investigate the proposed duality between the island and the defect extremal surface (DES) prescriptions using the fine-grained entanglement entropy in Karch-Ran…

Holographic Reflected Entropy: Islands and Defect Phases

Ankur Dey, Gautam Sengupta

We investigate the mixed state entanglement structure through the reflected entropy for disjoint radiation subsystems coupled to a 2d eternal brane world black hole in a time depen…

Holographic Entanglement Entropy in Janus deformed AdS Geometries

Ankit Anand, Himanshu Chourasiya, Ankur Dey +1

We investigate the time dependent entanglement entropy for boosted single intervals in interface conformal field theories (ICFTs) dual to Janus deformed AdS geometries. For…

Bridging Boundaries: , Double Holography, and Reflected Entropy

Debarshi Basu, Himanshu Chourasiya, Ankur Dey +1

We investigate the reflected entropy for bipartite mixed state configurations in a deformed boundary conformal field theory in dimensions (BCFT). The bulk dual i…
