Influence of quantum resonance-percolation trajectories in a disordered I layer on the critical current of a Josephson S-I-S junction

Formulas for a critical current and the magnitude of its mesoscopic structural fluctuations are obtained in the form of sums over quantum resonance-percolation trajectories [1] randomly formed in a disordered I layer and connecting opposite S banks of the junction at T = 0 in the energy region of tu...

Description
Summary:Formulas for a critical current and the magnitude of its mesoscopic structural fluctuations are obtained in the form of sums over quantum resonance-percolation trajectories [1] randomly formed in a disordered I layer and connecting opposite S banks of the junction at T = 0 in the energy region of tunnel S - I - S resonances ( S denotes the superconductor, I , insulator) for a tunnel junction with weak structural disorders (low impurity concentrations) in the I layer.
