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…
Measurement and feedback-driven adaptive dynamics in the classical and quantum kicked top
Mahaveer Prasad, Ahana Chakraborty, Thomas Iadecola +4
In classical dynamical systems, stochastic feedback can stabilize otherwise unstable periodic orbits, giving rise to distinct controlled and uncontrolled phases as the rate of cont…
Generating pairwise entanglement in periodically driven quantum spin chains with stochastic resetting
Sinchan Ghosh, Manas Kulkarni, K. Sengupta +1
We show that stochastic resetting may lead to finite entanglement between individual, spatially separated spins (pairwise entanglement) in the steady state of the spin chains drive…
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…
