Tunable topological phase in 2D ScVSn kagome material
Chidiebere I. Nwaogbo, Sanjib K. Das, Chinedu E. Ekuma
We investigate the topological properties of the vanadium-based 2D kagome metal ScVSn, a ferromagnetic material with a magnetic moment of 0.86 per atom. Using ab init…

Superconductivity in doped planar Dirac insulators: A renormalization group study
Sk Asrap Murshed, Sanjib Kumar Das, Bitan Roy
From a leading-order unbiased renormalization group analysis we here showcase the emergence of superconductivity (including the topological ones) from purely repulsive electron-ele…

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…
