Keywords: quantum pumping; quantum transport; spin current; Introduction The time-honored field of quantum transport has been evolving in the past 15 years in such a way that spin–orbit interaction

One is the spin version of quantum pumping – something that is not possible classically. A seminal paper by Thouless [3] pointed out that quantum mechanics

• gives the possibility of propagating a charge current in a circuit without an applied bias. It became clear later that quantum pumping obtained by varying one parameter in the Hamiltonian requires a nonlinear dependence of the current on the dynamics. Romeo and Citro [4] have discussed memory and

For time-dependent phenomena, scattering-matrix expressions have been obtained for quantum pumping [5][6], a process by which a direct current is generated through temporal variations of relevant

• vibrations on the electronic current. In the strictly adiabatic limit, this obviously has to reduce to the Landauer–Büttiker formula for the transport current. The leading adiabatic correction to the current in equilibrium is closely related to the phenomenon of quantum pumping, and we will see that our
