Floquet Majorana flat bands and emergent Cooper pair symmetries in wave magnetsuperconductor heterostructure
Subhendu Kumar Patra, Gaurab Kumar Dash, Manisha Thakurathi
We investigate the emergence of topological superconductivity at the two-dimensional heterostructure interface between a -wave magnet (pWM) and an -wave superconductor. By an…

Floquet multiple exceptional points with higher-order skin effect
Gaurab Kumar Dash, Subhendu Kumar Patra, Diptiman Sen +1
We investigate the rich non-equilibrium physics arising in periodically driven open quantum systems, specifically those realized within microcavity resonators, whose dynamics are g…

Fingerprint of Non-Hermiticity in d-wave Altermagnet
Gaurab Kumar Dash, Subhasis Panda, Snehasish Nandy
We develop the non-Hermitian counterpart of a new class of collinear magnets, dubbed altermagnets, delineated by net zero magnetization with momentum-dependent spin-splitting bands…
