Quantum resetting with memory
Gabriele de Mauro, Manas Kulkarni, Satya N. Majumdar
We introduce a quantum stochastic resetting protocol with uniform memory, in which each resetting event returns the system to a state visited at a time chosen uniformly from its en…
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…
Control transition in a temporally random classical spin chain
Elisha Shmalo, J. H. Pixley, Manas Kulkarni +2
We theoretically explore a phase transition between controlled and chaotic dynamics in a classical spin chain model subject to chaotic Hamiltonian dynamics and a contractive "contr…
Quantized Transport in Floquet Topological Insulators
Rekha Kumari, Manas Kulkarni, Abhishek Dhar
We study quantum transport in a periodically driven (Floquet) topological system coupled to static fermionic reservoirs. Using the Floquet nonequilibrium Green's-function (NEGF) fo…
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…
