Sector-resolved non-Bloch topology and nonlocal entanglement dynamics in a bond-dissipative Kitaev chain
Shaina Gandhi, Koustav Roy, Bilal Tanatar +1
A core characteristic of dissipative non-Hermitian topology is that the relaxation dynamics tracks the non-Bloch bulk-boundary correspondence, rendering an algebraic decay in the g…
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 le…
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).…
Non-Hermitian Aubry-André-Harper model with short- and long-range p-wave pairing
Shaina Gandhi, Jayendra N. Bandyopadhyay
We investigate a non-Hermitian Aubry-André-Harper model with short-range, as well as long-range p-wave pairing. Here, the non-Hermiticity is introduced through the onsite potentia…
