Ac-dc voltage profile and four point impedance of a quantum driven system
We investigate the behavior of the time-dependent voltage drop in a periodically driven quantum conductor sensed by weakly coupled dynamical voltages probes. We introduce the concepts of ac-dc local voltage and four point impedance in an electronic system driven by ac fields. We discuss the properti...

| Sumario: | We investigate the behavior of the time-dependent voltage drop in a periodically driven quantum conductor sensed by weakly coupled dynamical voltages probes. We introduce the concepts of ac-dc local voltage and four point impedance in an electronic system driven by ac fields. We discuss the properties of the different components of these quantities in a simple model of a quantum pump, where two ac voltages oscillating with a phase lag are applied at the walls of a quantum dot. © 2010 The American Physical Society. |
