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…
Localization and delocalization in networks with varied connectivity
Tamoghna Ray, Amit Dey, Manas Kulkarni
We study the phenomenon of localization and delocalization in a circuit-QED network with connectivity varying from finite-range to all-to-all coupling. We find a fascinating interp…
