Generating pairwise entanglement in periodically driven quantum spin chains with stochastic resetting
Sinchan Ghosh, Manas Kulkarni, K. Sengupta +1
We show that stochastic resetting may lead to finite entanglement between individual, spatially separated spins (pairwise entanglement) in the steady state of the spin chains drive…

Index-theoretic route to the subgap Andreev bands and topological response in Josephson junctions
Sinchan Ghosh, Srinjoy Ghosh, Arijit Kundu +1
We demonstrate that the subgap Andreev bound states in a transparent Josephson junction, comprising of either chiral or non-chiral superconductors, can be viewed as a consequence o…
