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 parametrs and bias conditions on the step amplitude, in view of an experimental check of the proposed phenomenon.

Abstract
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 parametrs and bias conditions on the step amplitude, in view of an experimental check of the proposed phenomenon.File in questo prodotto:
