Floquet scars and prethermal fragmentation in a driven spin-one chain
Krishanu Ghosh, Diptiman Sen, K. Sengupta
We study the periodic dynamics of a spin-one chain driven using a square-pulse protocol with amplitude and frequency . The Hamiltonian of the spin chain hosts a thermody…

Exact Floquet flat band and heating suppression via two-rate drive protocols
Tista Banerjee, Sayan Choudhury, K. Sengupta
We demonstrate the existence of exact Floquet flat bands implying strong violation of the eigenstate thermalization hypothesis in a large class of closed quantum many-body systems…
