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…

Selective spin transport through a quantum heterostructure: Transfer matrix method
Moumita Dey, Santanu K. Maiti
In the present work we propose that a one-dimensional quantum heterostructure composed of magnetic and non-magnetic atomic sites can be utilized as a spin filter for a wide range o…
