Quantum Dynamics of Small Josephson Junctions: An Application to Superconductivity in Granular Films (1986)This thesis is devoted to a study of the quantum dynamics of small Josephson junctions. Of interest are those features of the junction's behavior which depend explicitly on the quantum mechanical nature of the phase ...
