Collapse and revival of quantum many-body scars via Floquet engineering
Bhaskar Mukherjee, Sourav Nandy, Arnab Sen +2
The presence of quantum scars, athermal eigenstates of a many-body Hamiltonian with finite energy density, leads to absence of ergodicity and long-time coherent dynamics in closed…

Transport across junctions of pseudospin-one fermions
Sourav Nandy, K. Sengupta, Diptiman Sen
We study transport across ballistic junctions of materials which host pseudospin-one fermions as emergent low-energy quasiparticles. The effective low-energy Hamiltonians of such f…

Steady states of a quasiperiodically driven integrable system
Sourav Nandy, Arnab Sen, Diptiman Sen
Driven many-body quantum systems where some parameter in the Hamiltonian is varied quasiperiodically in time may exhibit nonequilibrium steady states that are qualitatively differe…
