Dissipation induced Majarona - and -modes in a driven Rashba nanowire
Koustabh Gogoi, Tanay Nag, Arnob Kumar Ghosh
Periodic drive is an intriguing way of creating topological phases in a non-topological setup. However, most systems are often studied as a closed system, despite being always in c…

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…

Topological characterization of a non-Hermitian ladder via Floquet non-Bloch theory
Koustav Roy, Koustabh Gogoi, Saurabh Basu
In this paper, we study a non-Hermitian (NH) ladder subjected to a variety of driving protocols. The driven system looses chiral symmetry (CS) whose presence is indispensable for i…
