    Notizen: Summary The dynamics of vortex lines in type-II superconductors are discussed from a quantum electrodynamic viewpoint. When a vortex line is set into motion, electric fields are generated. These play a dual role of providing electric-field energy storage («kinetic energy») and also generating normal electron energy dissipation. From these considerations, the mass density and the drag coefficients for vortices can be derived. Quantum mechanisms for vortex motions and nucleation are discussed.

    Bulk Josephson energies in multi-gap models of highT c superconductors (1991)

    Notizen: Abstract Multi-gap models of high temperature ceramic superconductors have been of considerable recent interest. For the case of a two-gap model (Δ1, and Δ2), there exist two separate electron pair condensate reservoirs, and a bulk Josephson free energy can be associated with electron pair transitions from one reservoir to the other. Thus, a “Josephson effect” can exist in two-gap models without the requirement of a weak link separating the two electron pair reservoirs in space. A single bulk sample Josephson electron pair free energy is here derived from the conventional BCS model of the superconducting state.
