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…
Coherence measure of ensembles with nonlocality without entanglement
Ayan Patra, Shiladitya Mal, Aditi Sen De
Irreversibility between preparation and discrimination processes is manifested in the indistinguishability of orthogonal product states via local operations and classical communica…
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…
Page Curves and Bath Deformations
Elena Caceres, Arnab Kundu, Ayan K. Patra +1
We study the black hole information problem within a semiclassically gravitating AdS black hole coupled to and in equilibrium with a -dimensional thermal conformal bath. We…
Efficient nonlinear witnessing of non-absolutely separable states with lossy detectors
Ayan Patra, Shiladitya Mal, Aditi Sen De
Entangled states are undoubtedly an integral part of various quantum information processing tasks. On the other hand, absolutely separable states which cannot be made entangled und…
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…
Reparametrization mode Ward Identities and chaos in higher-pt. correlators in CFT
Arnab Kundu, Ayan K. Patra, Rohan R. Poojary
Recently introduced reparametrization mode operators in CFTs have been shown to govern stress tensor interactions the shadow operator formalism and seem to govern the effecti…
