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…
Chaos and Complexity from Quantum Neural Network: A study with Diffusion Metric in Machine Learning
Sayantan Choudhury, Ankan Dutta, Debisree Ray
In this work, our prime objective is to study the phenomena of quantum chaos and complexity in the machine learning dynamics of Quantum Neural Network (QNN). A Parameterized Quantu…
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

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

The Cosmological OTOC: Formulating new cosmological micro-canonical correlation functions for random chaotic fluctuations in Out-of-Equilibrium Quantum Statistical Field Theory
Sayantan Choudhury
The out-of-time-ordered correlation (OTOC) function is an important new probe in quantum field theory which is treated as a significant measure of random quantum correlations. In t…
