Microscopic quantum tunneling in Josephson junctions
Golub A. A. , Iordatii V. P.
The effect of dissipation on microscopic quantum tunneling in Josephson junctions is studied. It is shown that dissipation increases the lifetime of the metastable state of the junction. It is found that the tunneling probability can be clearly separated into quantum-mechanical tunneling in the absence of dissipation and dissipation-related tunneling only for small dissipation.
