More Book Details

Description of the Book:

We study the transport properties of setups with one and two mesoscopic rings threaded by ac magnetic fluxes of the form Phi(t)=Phi^{dc} + Phi^{ac} cos(Omega_0 t + delta) and connected to two different particle reservoirs. We analyze the conditions to generate a pumped dc current in the adiabatic regime. We also study the symmetry properties of the induced dc current as a function of the static component of the flux, Phi^{dc}, with and without a dc bias voltage applied at the reservoirs. We analyze, in particular, the validity of the Onsager-Casimir relations for different configurations of the setups
