Reflected entropy and islands in a braneworld cosmology
Debarshi Basu, Ashish Chandra, Himanshu Chourasiya
This work investigates the nature of mixed state entanglement and correlation in a braneworld cosmological model, where the bulk geometry is described by an eternal BTZ black hole…
Islands and dynamics at the interface
Mir Afrasiar, Debarshi Basu, Ashish Chandra +2
We investigate a family of models described by two holographic CFTs coupled along a shared interface. The bulk dual geometry consists of two AdS spacetimes truncated by a s…
Reflected Entropy for Communicating Black Holes II: Planck Braneworlds
Mir Afrasiar, Jaydeep Kumar Basak, Ashish Chandra +1
We obtain the reflected entropy for bipartite mixed state configurations of two adjacent and disjoint subsystems at a finite temperature in finite-sized non-gravitating reservoirs…
Reflected Entropy for Communicating Black Holes I: Karch-Randall Braneworlds
Mir Afrasiar, Jaydeep Kumar Basak, Ashish Chandra +1
We obtain the reflected entropy for bipartite mixed state configurations of two adjacent and disjoint intervals at a finite temperature in s with two distinct boundaries th…
Islands for Entanglement Negativity in Communicating Black Holes
Mir Afrasiar, Jaydeep Kumar Basak, Ashish Chandra +1
We obtain the holographic entanglement negativity for bipartite mixed states at a finite temperature in baths described by conformal field theories dual to configurations involving…
Entanglement Wedge in Flat Holography and Entanglement Negativity
Debarshi Basu, Ashish Chandra, Vinayak Raj +1
We establish a construction for the entanglement wedge in asymptotically flat bulk geometries for subsystems in dual -dimensional Galilean conformal field theories in the co…
Entanglement Negativity in Flat Holography
Debarshi Basu, Ashish Chandra, Himanshu Parihar +1
We advance holographic constructions for the entanglement negativity of bipartite states in a class of dimensional Galilean conformal field theories dual to asymptotically…
Towards a Classification of Two-Character Rational Conformal Field Theories
A. Ramesh Chandra, Sunil Mukhi
We provide a simple and general construction of infinite families of consistent, modular-covariant pairs of characters satisfying the basic requirements to describe two-character R…
Observation of micro-macro entanglement of light
A. I. Lvovsky, R. Ghobadi, A. Chandra +2
Schroedinger's famous thought experiment involves a (macroscopic) cat whose quantum state becomes entangled with that of a (microscopic) decaying nucleus. The creation of such micr…
