Quantum Geometry Driven Optical Responses in 1T-MX Monolayers: A Symmetry-Constrained Slater-Koster Tight-Binding Approach
Bikram Baruah, Snehasish Nandy, Subhasis Panda
Centrosymmetric 1T-MX monolayers(MLs) have attracted considerable attention owing to their intriguing transport properties and potential technological applications arising from…
Magnetic field Controlled Anderson Delocalization in a Spinful Non-Hermitian Chain
Moirangthem Sanahal, Subhasis Panda, Snehasish Nandy
Anderson localization (AL) and the non-Hermitian skin effect (NHSE) represent two paradigmatic localization phenomena driven, respectively, by disorder and non-Hermiticity. In one-…
Gauge Field Induced Unconventional Skin Effect in Spinful Non-Hermitian Systems
Moirangthem Sanahal, Subhasis Panda, Snehasish Nandy
The non-Hermitian skin effect (NHSE), a hallmark of non-Hermitian systems, stems from the topological nature of complex energy spectra, typically characterized by a non-zero spectr…
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…
