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…
Skin effect and dynamical delocalization in non-Hermitian quasicrystals with spin-orbit interaction
Aditi Chakrabarty, Sanjoy Datta
The investigations of the spectral and dynamical delocalization-localization (DL) transition have revealed intriguing features in a wide range of non-Hermitian systems. The present…
Effect of spin-orbit coupling in one-dimensional quasicrystals with power-law hopping
Deepak Kumar Sahu, Sanjoy Datta
In the one-dimensional quasiperiodic Aubry-André-Harper Hamiltonian with nearest-neighbor hopping, all single-particle eigenstates undergo a phase transition from ergodic to locali…
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…
