Generation of pure spin currents via nonadiabatic quantum pumping in an antiferromagnetic chain
Leila Eslami, Fatemeh Bourbour, Somaieh Ahmadi +1
In this study, quantum spin pumping in an antiferromagnetic chain driven by time-dependent potential is investigated. The aim is to explore the possibility of generating and contro…

Quantum charge pumping in helical systems: A comparative study of short- and long-range hopping
Leila Eslami, Santanu K. Maiti, Fatemeh Bourbour
Using the Keldysh non-equilibrium Green's function approach, we investigate charge pumping through a single-stranded helical structure described by a tight-binding model that inclu…
