摘要

A macroscopic quantum theory for the capacitively-coupled intrinsic Josephson junctions (IJJ's) is constructed. We clarify the multi junction effect for the macroscopic quantum tunneling (MQT) to the first resistive branch. It is shown that the escape rate is greatly enhanced by the capacitive coupling between junctions. We also discuss the origin of the N-2-enhancement in the escape rate observed in the uniformly switching in Bi-2212 IJJ's.
