Pure Spin Bulk Photovoltaic Effect in an Altermagnetic Higher-Order Topological Insulator
Sibgat Ulah, Ankan Bhattacharyya, Manisha Thakurathi
We investigate the bulk photovoltaic effect (BPVE) in a -symmetric two-dimensional heterostructure consisting of a topological insulator coupled to a -wave altermagnet. To d…
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…
-wave magnet driven field-free Josephson diode effect
Lovy Sharma, Bimal Ghimire, Manisha Thakurathi
Recently, the superconducting diode effect (SDE), characterized by unequal critical currents in opposite directions, has been observed experimentally and predicted theoretically in…
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…
Tunable Josephson diode effect in singlet superconductor-altermagnet-triplet superconductor junctions
Lovy Sharma, Manisha Thakurathi
Recently discovered phase of collinear magnet called, altermagnet breaks time reversal symmetry (TRS), exhibits momentum-dependent spin-splitting of band structure with zero net ma…
