Signatures of fragmentation for periodically driven fermions
Somsubhra Ghosh, Indranil Paul, K. Sengupta
We study the possible signatures of prethermal strong Hilbert space fragmentation (HSF) for one-dimensional (1D) fermions subjected to a periodic drive. We extend the results of Ph…
A Floquet perturbation theory for periodically driven weakly-interacting fermions
Roopayan Ghosh, Bhaskar Mukherjee, K. Sengupta
We compute the Floquet Hamiltonian for weakly interacting fermions subjected to a continuous periodic drive using a Floquet perturbation theory (FPT) with the interaction amp…
Restoring coherence via aperiodic drives in a many-body quantum system
Bhaskar Mukherjee, Arnab Sen, Diptiman Sen +1
We study the unitary dynamics of randomly or quasi-periodically driven tilted Bose-Hubbard (tBH) model in one dimension deep inside its Mott phase starting from a sy…
Bosons with incommensurate potential and spin-orbit coupling
Sayak Ray, Bhaskar Mukherjee, S. Sinha +1
We chart out the phase diagram of ultracold `spin-half' bosons in a one-dimensional optical lattice in the presence of Aubry-André (AA) potential and with spin-orbit (SO) and Raman…
Signatures and conditions for phase band crossings in periodically driven integrable systems
Bhaskar Mukherjee, Arnab Sen, Diptiman Sen +1
We present generic conditions for phase band crossings for a class of periodically driven integrable systems represented by free fermionic models subjected to arbitrary periodic dr…
Tuning towards dynamic freezing using a two-rate protocol
Satyaki Kar, Bhaskar Mukherjee, K. Sengupta
We study periodically driven closed quantum systems where two parameters of the system Hamiltonian are driven with frequencies and . We show that such drives may b…
