Localization transitions in non-Hermitian quasiperiodic lattice
Aruna Prasad Acharya, Sanjoy Datta
The delocalization-localization (DL) transition in non-Hermitian systems exhibits intriguing features distinct from their Hermitian counterparts. In this study, we investigate the…
Localization, -Symmetry Breaking and Topological Transitions in non-Hermitian Quasicrystals
Aruna Prasad Acharya, Aditi Chakrabarty, Deepak Kumar Sahu +1
According to the topological band theory of a Hermitian system, the different electronic phases are classified in terms of topological invariants, wherein the transition between th…
Self-duality of One-dimensional Quasicrystals with Spin-Orbit Interaction
Deepak Kumar Sahu, Aruna Prasad Acharya, Debajyoti Choudhuri +1
Non-interacting spinless electrons in one-dimensional quasicrystals, described by the Aubry-André-Harper (AAH) Hamiltonian with nearest neighbour hopping, undergoes metal to insula…
