EFFECTS OF JUNCTION PARAMETERS ON THE RESONANT MACROSCOPIC QUANTUM TUNNELING IN SMALL JOSEPHSON-JUNCTIONS

Within the well-established quantum picture of a Josephson junction, it has been shown that the possibility of a resonant macroscopic quantum tunnelling can produce sharp voltage peaks in the current-voltage characteristics. We investigate the effects of the junction parameters and bias conditions on the step amplitude, in view of an experimental check of the proposed phenomenon.
