Aspects of holographic timelike entanglement entropy in black hole backgrounds
Mir Afrasiar, Jaydeep Kumar Basak, Keun-Young Kim
We study the holographic construction of timelike entanglement entropy (tEE) in black hole backgrounds in Lorentzian geometries. The holographic tEE is realized through extremal su…
Holographic Timelike Entanglement Entropy in Non-relativistic Theories
Mir Afrasiar, Jaydeep Kumar Basak, Dimitrios Giataganas
Timelike entanglement entropy is a complex measure of information that is holographically realized by an appropriate combination of spacelike and timelike extremal surfaces. This m…
Timelike Entanglement Entropy and Phase Transitions in non-Conformal Theories
Mir Afrasiar, Jaydeep Kumar Basak, Dimitrios Giataganas
We propose a holographic formalism for a timelike entanglement entropy in non-conformal theories. This pseudoentropy is a complex-valued measure of information, which, in holograph…
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…
Covariant holographic reflected entropy in
Mir Afrasiar, Himanshu Chourasiya, Vinayak Raj +1
We substantiate a covariant proposal for the holographic reflected entropy in s dual to non-static geometries from the bulk extremal entanglement wedge cross section in…
Time evolution of spread complexity in quenched Lipkin-Meshkov-Glick model
Mir Afrasiar, Jaydeep Kumar Basak, Bidyut Dey +2
We use the spread complexity of a time evolved state after a sudden quantum quench in the Lipkin-Meshkov-Glick (LMG) model prepared in the ground state as a probe of quantum phase…
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…
Holographic Entanglement Negativity for Disjoint Subsystems in Conformal Field Theories with a Conserved Charge
Mir Afrasiar, Jaydeep Kumar Basak, Vinayak Raj +1
We investigate the extension of a holographic construction for the entanglement negativity of two disjoint subsystems in proximity to s with a conserved charge dual to bulk…
