Exact and mean-field analysis of the role of Hubbard interactions on flux driven circular current in a quantum ring
Rahul Samanta, Santanu K. Maiti, Shreekantha Sil
We investigate circular current in both ordered and disordered Hubbard quantum rings threaded by magnetic flux, employing exact diagonalization and the Hartree-Fock mean-field appr…
New perspective on symmetry breaking in a clean antiferromagnetic chain: Spin-selective transport and NDR phenomenon
Prabhab Patra, Santanu K. Maiti
The primary requirement for achieving spin-selective electron transfer in a nanojunction possessing a magnetic system with zero net magnetization is to break the symmetry between t…
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…
Antiferromagnetic diamond network as an efficient spin filter: Proposition of a spin-specific semi-conducting behavior
Debjani Das Gupta, Santanu K. Maiti
We propose, for the first time, that an array of diamond plaquettes, each possessing vanishing net magnetization, can achieve complete spin polarization over a broad bias window. F…
