Persistent Charge and Spin Currents in a Ferromagnetic Hatano-Nelson Ring
Sourav Karmakar, Sudin Ganguly, Santanu K. Maiti
We investigate persistent charge and spin currents in a ferromagnetic Hatano-Nelson ring with anti-Hermitian intradimer hopping, where non-reciprocal hopping generates a synthetic…
Spin caloritronics in collinear ferromagnetic helical structures under irradiation
Sudin Ganguly, Moumita Dey, Santanu K. Maiti
We study the charge and spin-dependent thermoelectric response of a ferromagnetic helical system irradiated by arbitrarily polarized light, using a tight-binding framework and the…
Photo-induced directional transport in extended SSH chains
Usham Harish Kumar Singha, Kallol Mondal, Sudin Ganguly +1
We investigate the current-voltage characteristics of an extended Su-Schrieffer-Heeger (SSH) chain under irradiation by arbitrarily polarized light, demonstrating its potential as…
Reentrant localization in a quasiperiodic chain with correlated hopping sequences
Sourav Karmakar, Sudin Ganguly, Santanu K. Maiti
Quasiperiodic systems are known to exhibit localization transitions in low dimensions, wherein all electronic states become localized beyond a critical disorder strength. Interesti…
