Circuit Complexity From Cosmological Islands
Sayantan Choudhury, Satyaki Chowdhury, Nitin Gupta +6
Recently in various theoretical works, path-breaking progress has been made in recovering the well-known Page Curve of an evaporating black hole with Quantum Extremal Islands, prop…
Quantum aspects of chaos and complexity from bouncing cosmology: A study with two-mode single field squeezed state formalism
Parth Bhargava, Sayantan Choudhury, Satyaki Chowdhury +4
, a well known computational technique has recently become the backbone of the physics community to probe the chaotic behaviour and random quantum fluctuations…
The Generalized OTOC from Supersymmetric Quantum Mechanics: Study of Random Fluctuations from Eigenstate Representation of Correlation Functions
Kaushik Y. Bhagat, Baibhab Bose, Sayantan Choudhury +7
The concept of out-of-time-ordered correlation (OTOC) function is treated as a very strong theoretical probe of quantum randomness, using which one can study both chaotic and non-c…
QMetrology from QCosmology: Study with Entangled Two Qubit Open Quantum System in De Sitter Space
Sayantan Choudhury, Satyaki Chowdhury, Nitin Gupta +1
In this paper, our prime objective is to apply the techniques of parameter estimation theory and the concept of Quantum Metrology in the form of Fisher Information to investigate t…
Indirect detection of Cosmological Constant from interacting open quantum system
Subhashish Banerjee, Sayantan Choudhury, Satyaki Chowdhury +4
We study the indirect detection of Cosmological Constant from an open quantum system of interacting spins, weakly interacting with a thermal bath, a massless scalar field minimally…
