Localization transitions in an open quasiperiodic ladder
Suparna Sarkar, Soumya Satpathi, Swapan K. Pati
We investigate localization transition in an open quasiperiodic ladder where the quasiperiodicity is described by the Aubry-André-Harper model. While previous studies have shown t…

Phases and phase transtions in one-dimensional alternating mixed spin (1/2-1) chain: effects of frustration and anisotropy
Soumya Satpathi, Suparna Sarkar, Swapan K. Pati
We investigate the phases and phase-transitions in one-dimensional alternating mixed-spin (1/2-1) chain in the presence of both frustration and anisotropy. Frustration is introduce…

Enhancement of persistent current in a non-Hermitian disordered ring
Suparna Sarkar, Soumya Satpathi, Swapan K. Pati
We have studied the Aharonov-Bohm flux-induced magnetic response of a disordered non-Hermitian ring. The disorder is introduced through an on-site quasiperiodic potential described…
