Photon-assisted AC transport through coherently driven mesoscopic systems has been studied by employing a transfer-matrix method. For a driven double-barrier system as a simple model of a quantum dot, we show that the AC current due to quantum interference between di erent sideband states depends on
We have measured dissipative (real) and non-dissipative (imaginary) magneto-conductance of arrays of disconnected GaAs-GaAlAs mesoscopic rings and square dots in the MHz-GHz range. The samples are coupled to a highly sensitive electromagnetic multimode superconducting micro-resonator and lead to a p
Microwave irradiation of Nb-InAs-Nb single-junctions demonstrates that the half-integer Shapiro step is caused by ac nonequilibrium supercurrents. In addition, nonequilibrium dc supercurrents are observed as a conductance enhancement around zero bias. Both effects persist to temperatures integer Sha
