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…

Topological insulators on fractal lattices: A general principle of construction
Daniel J. Salib, Aiden J. Mains, Bitan Roy
Fractal lattices, featuring the self-similarity symmetry, are often geometric descents of parent crystals, possessing all their discrete symmetries (such as rotations and reflectio…

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…
