Chaos from quantum bath fluctuations
Ilan Baud, Tamoghna Ray, Mahaveer Prasad +2
The effect of a large environment on a finite-size quantum mechanical system is two-fold: It brings dissipation, but also fluctuations of thermal and quantum origin. While dissipat…
Quantum dynamics in lattices in presence of bulk dephasing and a localized source
Tamoghna Ray, Katha Ganguly, Dario Poletti +2
The aim of this work is to study the dynamics of quantum systems subjected to a localized fermionic source in the presence of bulk dephasing. We consider two classes of one-dimensi…
Page curve like dynamics in Interacting Quantum Systems
Tamoghna Ray, Abhishek Dhar, Manas Kulkarni
We study the dynamics of entanglement in a one-dimensional spin- chain, with and without integrability-breaking interactions, that is connected to a bath. We start from…
Ergodic and chaotic properties in Tavis-Cummings dimer: quantum and classical limit
Tamoghna Ray, Manas Kulkarni
We investigate two key aspects of quantum systems by using the Tavis-Cummings dimer system as a platform. The first aspect involves unraveling the relationship between the phenomen…
