We investigate quantum dynamics of the superconducting phase in intrinsic Josephson junctions of layered high-T c superconductors motivated by a recent experimental observation for the switching rate enhancement in the low temperature quantum regime. We pay attention to only the capacitive coupling
We have theoretically investigated macroscopic quantum tunneling (MQT) for a stack of capacitively and inductively coupled intrinsic-junctions. By use of the functional integral method, we have analytically derived the MQT escape rate and found that the inductive coupling reduces the potential barri
