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...
