Transport characteristics in Hermitian and non-Hermitian Fibonacci rings: A comparative study
Souvik Roy, Santanu K. Maiti
We present an extensive theoretical analysis of transport and circular currents and the associated induced magnetic fields in Fibonacci rings, explored in both Hermitian and non-He…

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…

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 (…
