Discrete time crystal order in spin chains enabled by Floquet flat bands
Mahbub Rahaman, Analabha Roy
We propose a novel protocol to realize discrete time-crystal (DTC) order in clean, periodically driven spin- chains. In each drive cycle, a global spin flip is followed by a t…
Phase Crossover induced by Dynamical Many Body Localization in Periodically Driven Long-Range Spin Systems
Mahbub Rahaman, Takashi Mori, Analabha Roy
Dynamical many-body freezing occurs in periodic transverse field-driven integrable quantum spin systems. Under freezing conditions, quantum dynamics causes practically infinite hys…
Quantum effects in the cooperative scattering of light by atomic clouds
Lorenzo Pucci, Analabha Roy, Tiago Santiago do Espirito Santo +3
Scattering of classical light by atomic clouds induces photon-mediated effective long-range interactions between the atoms and leads to cooperative effects even at low atomic densi…
Simulation of Quantum Spin Dynamics by Phase Space Sampling of BBGKY Trajectories
Lorenzo Pucci, Analabha Roy, Michael Kastner
A numerical method, suitable for the simulation of the time evolution of quantum spin models of arbitrary lattice dimension, is presented. The method combines sampling of the Wigne…
The fate of dynamical many-body localization in the presence of disorder
Analabha Roy, Arnab Das
Dynamical localization is one of the most startling manifestations of quantum interference, where the evolution of a simple system is frozen out under a suitably tuned coherent per…
Nonequilibrium Dynamics of Ultracold Fermi Superfluids
Analabha Roy
The aim of this mini review is to survey the literature on the study of nonequilibrium dynamics of Fermi superfluids in the BCS and BEC limits, both in the single channel and dual…
