| Abstract: | Quantum dynamics, in particular, macroscopic quantum tunneling in Josephson junctions coupled with resonant electro-magnetic modes is studied in the paper. For a typical case, a small junction connected to a superconducting transmission line, explicit Lagragians and Euclidean actions are derived which can be used to compute the quantum tunneling rates in a current-biased or an rf SQUID setup. It is suggested that this system may be used for more determinate macroscopic tunneling and other measurements. |
