Sector-resolved non-Bloch topology and nonlocal entanglement dynamics in a bond-dissipative Kitaev chain

Shaina Gandhi, Koustav Roy, Bilal Tanatar +1

A core characteristic of dissipative non-Hermitian topology is that the relaxation dynamics tracks the non-Bloch bulk-boundary correspondence, rendering an algebraic decay in the g…

Floquet generation of hybrid-order topology and $Z_{2}$ -like bipolar localization

Koustav Roy, Latu Kalita, Bilal Tanatar +1

Periodic driving offers a powerful tool to engineer topological phases and even induce phase transitions that are inaccessible in static settings. In this work, we demonstrate that…
