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…

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 ( $I ¨ _{x y}$ ), thermal ( $I^º_{x y}$ ), and spin ( $I ¨ _{x y}^{s p}$ ) Hall, and…
