Controlling Dissipative Topology Through Floquet Driving: From Transient Diagnostics to Boundary States Isolation
Koustav Roy, Shahroze Shahab, Saurabh Basu
Engineering dissipative dynamics in open quantum systems is under active focus, especially in topological settings where resilient edge modes are expected to exhibit decay rates di…
Floquet Non-Bloch Formalism for a Non-Hermitian Ladder: From Theoretical Framework to Topolectrical Circuits
Koustav Roy, Dipendu Halder, Koustabh Gogoi +2
Periodically driven systems intertwined with non-Hermiticity opens a rich arena for topological phases that transcend conventional Hermitian limits. The physical significance of th…
Floquet-engineered diode performance in a Majorana-quantum dot Josephson junction
Koustav Roy, Gourab Paul, Debika Debnath +2
We study nonreciprocal signatures of Josephson current (JC) in a quantum dot (QD)-based Josephson junction (JJ) that comprises of two periodically driven Kitaev chains (KCs) couple…
