Holographic Black Hole Formation and Scrambling in Time-Ordered Correlators
Pratyusha Chowdhury, Felix M. Haehl, Adrián Sánchez-Garrido +1
We describe a holographic mechanism for black hole formation via the collision of two shock waves in three-dimensional anti-de Sitter spacetime. In the dual conformal field theory…
Wigner negativity, random matrices and gravity
Ritam Basu, Pratyusha Chowdhury, Anirban Ganguly +3
Given a choice of an ordered, orthonormal basis for a -dimensional Hilbert space, one can define a discrete version of the Wigner function -- a quasi-probability distribution wh…
Loops, Recursions, and Soft Limits for Fermionic Correlators in (A)dS
Chandramouli Chowdhury, Pratyusha Chowdhury, Radu N. Moga +1
Study of correlation functions in AdS/CFT and in-in correlators in de Sitter space often requires the computation of Witten diagrams. Due to the complexity of evaluating radial int…
Fate of entanglement between two Unruh-DeWitt detectors due to their motion and background temperature
Pratyusha Chowdhury, Bibhas Ranjan Majhi
We investigate the fate of initial entanglement between two accelerated detectors with respect to an observer attached to one of the detectors. Both and spacetime d…
Wave and particle properties can be spatially separated in a quantum entity
Pratyusha Chowdhury, Arun Kumar Pati, Jing-Ling Chen
Wave and particle are two fundamental properties of Nature. The wave-particle duality has indicated that a quantum object may exhibit the behaviours of both wave and particle, depe…
Instability Zones in the Dynamics of a Quantum Mechanical Quasiperiodic Parametric Oscillator
Subhadip Biswas, Pratyusha Chowdhury, Jayanta K Bhattacharjee
Quasi-periodically driven quantum parametric oscillators have been the subject of several recent investigations. Here we show that for such oscillators, the instability zones of th…
Social Advantage with Mixed Entangled States
Aritra Das, Pratyusha Chowdhury
It has been extensively shown in past literature that Bayesian Game Theory and Quantum Non-locality have strong ties between them. Pure Entangled States have been used, in both com…
