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 (…

Spin filtration in a single-stranded antiferromagnetic helix with slowly varying disorder: Higher order electron hopping
Suparna Sarkar, Santanu K. Maiti, David Laroze
This work explores spin filtration in a helical magnetic system within a tight-binding framework, where neighboring magnetic moments are aligned antiparallel. The helix experiences…
