Abstract:
We consider a microscopic model for a one-dimensional ring of non-interacting electrons threaded by a magnetic flux of the form Φ(t)= Φ0Φ1cos( Ω0t). The ring is attached to two reservoirs at which a bias voltage is applied. We focus on small amplitudes of Φ1, and we analyze the behavior of the conductance as a function of Φ0. We solve the problem by means of non-equilibrium Green function techniques. © 2011 Elsevier B.V. All rights reserved.
