Emergence of Non-Hermitian Magic Angles and Topological Phase Transitions in Twisted Bilayer - Lattices
Shaina Gandhi, Gourab Paul, Srijata Lahiri +1
We investigate the flat-band properties and topological phase transitions in a non-Hermitian twisted bilayer lattice. Here, non-Hermiticity is introduced via Hatano-Nelson-…
Investigating topological in-gap states in non-Hermitian quasicrystal with unconventional -wave pairing
Shaina Gandhi, Jayendra N. Bandyopadhyay
The interplay of onsite quasiperiodic potential, superconductivity, and non-Hermiticity is explored in a non-Hermitian unconventional superconducting quasicrystal described by Aubr…
Superconducting -wave pairing effects on one-dimensional non-Hermitian quasicrystals with power law hopping
Shaina Gandhi, Jayendra N. Bandyopadhyay
We study the effects of superconducting -wave pairing on the non-Hermitian Aubry-André-Harper model with power-law hopping. For the case of short-range hopping, weak pairing lea…
Transport properties in a two-dimensional Su-Schrieffer-Heeger model in Quantum Hall Regime
Aruna Gupta, Shaina Gandhi, Niladri Sarkar +1
We investigate the transport properties of a two-dimensional Su-Schrieffer-Heeger (2D SSH) model in the quantum Hall regime using non-equilibrium Green's function formalism (NEGF).…
