Abstract

We analyze the problem of supercurrent instability in highly transparent weak links. We identify several macroscopic quantum tunneling (MQT) regimes and predict a non-trivial non-monotonous dependence of the switching current distribution on temperature which can be observed in MQT experiments with transparent superconducting weak links.
