On the Quasiparticle- and Super-Current at the Finite Temperature Josephson Junction
In the temperature dependent reconstructed quantum mechanics over the limiting Gibbs state for two weakly coupled superconductors the effective dynamics is worked out and the current operator is expressed in terms of gauge covariant quasi-particle and condensed Cooper pair fields, where only the latter exhibit macroscopic quantum features.
