Quantized electrical, thermal, and spin transports of non-Hermitian clean and dirty two-dimensional topological insulators and superconductors
Sanjib Kumar Das, Bitan Roy
From lattice-regularized models, devoid of any non-Hermitian (NH) skin effects, here we compute the electrical (), thermal (), and spin () Hall, and th…

From local spin nematicity to altermagnets: Footprints of band topology
Sanjib Kumar Das, Bitan Roy
Altermagnets are crystallographic rotational symmetry breaking spin-ordered states, possessing a net zero magnetization despite manifesting Kramer's non-degenerate bands. Here, we…

Model non-Hermitian topological operators without skin effect: A general principle of construction
Daniel J. Salib, Sanjib Kumar Das, Bitan Roy
We propose a general principle of constructing non-Hermitian (NH) operators for insulating and gapless topological phases in any dimension () that over an extended NH parameter…
