| Abstract: | Summary 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. |
