Topological phase transition in fluctuating imaginary gauge fields
Bikashkali Midya
We investigate the exact solvability and point-gap topological phase transitions in non-Hermitian lattice models. These models incorporate site-dependent nonreciprocal hoppings $J…

Non-Hermitian tuned topological band gap
Bikashkali Midya
Externally controllable band gap properties of a material is crucial in designing optoelectronic devices with desirable properties on-demand. Here, a possibility of single paramete…

Dirac electron in graphene under supersymmetry generated magnetic fields
Bikashkali Midya, David J Fernández
We use supersymmetry transformations to obtain new one parameter family of inhomogeneous magnetic fields for which the massles…
