Anomalous persistent current in a 1D dimerized ring with aperiodic site potential: Non-interacting and interacting cases
Souvik Roy, Santanu K. Maiti, David Laroze
In this work, we investigate the magnetic response by examining flux-driven circular currents in a Su-Schrieffer-Heeger (SSH) tight-binding (TB) ring threaded by an Aharonov-Bohm (…

Flux-Driven Circular Current in a Non-Hermitian Dimerized Aharonov-Bohm Ring: Impact of Physical Gain and Loss
Souvik Roy, Santanu K. Maiti
In the present theoretical work, we numerically explore magnetic response of a tight-binding dimerized ring subjected to Aharonov-Bohm (AB) flux and environmental interactions. Spe…
