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…
Half-metallicity and two-dimensional hole gas at the (001) surface
Soumyasree Jena, Sanjoy Datta
The electronic structure and thermodynamic stability of tetragonal (001) surfaces have been investigated using density functional theory. In this work, four different…
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…
