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…

Integrable Floquet Time Crystals in One Dimension
Rahul Chandra, Mahbub Rahaman, Soumyabroto Majumder +2
We demonstrate the realization of a Discrete Time-Crystal (DTC) phase in a family of periodically driven, one-dimensional quadratic lattice Hamiltonians that can be obtained using…

Time crystal embodies chimeralike state in periodically driven quantum spin system
Mahbub Rahaman, Akitada Sakurai, Analabha Roy
Chimera states are a captivating occurrence in which a system composed of multiple interconnected elements exhibits a distinctive combination of synchronized and desynchronized beh…
