We study the normal state conductance and the Josephson current in a superconductor-2DEG-superconductor structure where the size/shape of the 2DEG-region can be modified by an additional side-gate electrode. The considered transport properties follow from the retarded Green function which we compute

The supercurrents in two mesoscopic Josephson junctions in the presence of the quantized light fields are studied. The states of the light fields discussed in this paper include squeezed coherent states, thermal states, even and odd coherent states. The Shapiro dc currents and the even-order fluctua
