Bias-driven circular currents in a quantum ring: Effects of electron-electron and electron-phonon interactions
Moumita Mondal, Santanu K. Maiti
The phenomenon of bias-driven circular charge and spin currents in a ring nanojunction is investigated in the presence of electron-electron (e-e) and electron-phonon (e-ph) interac…
Phonon mediated spin polarization in a one-dimensional Aubry-Andre-Harper chain
Moumita Mondal, Santanu K. Maiti
A comparative study of electronic transport and spin polarization between clean and Aubry-Andre-Harper chains in the presence of electron-electron (e-e) and electron-phonon (e-ph)…
Bias driven circular current in a ring nanojunction: Critical role of environmental interaction
Moumita Mondal, Santanu K. Maiti
The specific role of environmental interaction on bias driven circular current in a ring nanojunction is explored within a tight-binding framework based on wave-guide theory. The e…
Bias induced circular current in a loop nanojunction with AAH modulation: Role of hopping dimerization
Moumita Mondal, Santanu K. Maiti
In this work, we put forward, for the first time, the interplay between correlated disorder and hopping dimerization on bias driven circular current in a loop conductor that is cla…
