Bath deformations, islands and holographic complexity
Aranya Bhattacharya, Arpan Bhattacharyya, Pratik Nandy +1
Considering a doubly holographic model, we study the evolution of holographic subregion complexity corresponding to deformations of bath state by a relevant scalar operator, which…
Complexity for Open Quantum System
Arpan Bhattacharyya, Tanvir Hanif, S. Shajidul Haque +1
We study the complexity for an open quantum system. Our system is a harmonic oscillator coupled to a one-dimensional massless scalar field, which acts as the bath. Specifically, we…
Prospects for determining the nature of the secondaries of extreme mass-ratio inspirals using the spin-induced quadrupole deformation
Mostafizur Rahman, Arpan Bhattacharyya
The measurement of multipole moments of astrophysical objects through gravitational wave (GW) observations provides a novel way to distinguish black holes from other astrophysical…
Quantum Information Scrambling: From Holography to Quantum Simulators
Arpan Bhattacharyya, Lata Kh Joshi, Bhuvanesh Sundar
In this review, we present the ongoing developments in bridging the gap between holography and experiments. To this end, we discuss information scrambling and models of quantum tel…
Partial islands and subregion complexity in geometric secret-sharing model
Aranya Bhattacharya, Arpan Bhattacharyya, Pratik Nandy +1
We compute the holographic subregion complexity of a radiation subsystem in a geometric secret-sharing model of Hawking radiation in the "complexity = volume" proposal. The model i…
Ringdown of Charged Compact Objects using Membrane Paradigm
Mostafizur Rahman, Arpan Bhattacharyya
Although the black holes are an integral part of the standard model of astrophysics and cosmology, their existence poses some serious fundamental problems. In recent years, several…
Islands and complexity of eternal black hole and radiation subsystems for a doubly holographic model
Aranya Bhattacharya, Arpan Bhattacharyya, Pratik Nandy +1
We study the entanglement islands and subsystem volume complexity corresponding to the left/ right entanglement of a conformal defect in -dimensions in Randall-Sundrum (RS) bran…
