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…
One-dimensional spin-orbit coupled Dirac system with extended -wave superconductivity: Majorana modes and Josephson effects
Adithi Udupa, Abhishek Banerjee, K. Sengupta +1
Motivated by the spin-momentum locking of electrons at the boundaries of topological insulators, we study a one-dimensional system of spin-orbit coupled massless Dirac electrons wi…
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…
Josephson junctions of multiple superconducting wires
Oindrila Deb, K. Sengupta, Diptiman Sen
We study the spectrum of Andreev bound states and Josephson currents across a junction of superconducting wires which may have - or -wave pairing symmetries and develop a…
Low-frequency phase diagram of irradiated graphene and periodically driven spin-1/2 chain
Bhaskar Mukherjee, Priyanka Mohan, Diptiman Sen +1
We study the Floquet phase diagram of two-dimensional Dirac materials such as graphene and the one-dimensional (1D) spin-1/2 model in a transverse field in the presence of per…
