| Abstract: | The formulas in which the lower critical field and its mesoscopic structural fluctuations in the energy range of tunnel resonances of a long S-I-S (superconductor-insulator-superconductor) tunnel junction with weak (low impurity concentrations) structural disorder in the I layer at T = 0 are represented as sums over quantum resonant percolation trajectories (quantum jumpers), randomly formed in the disordered I layer 1], are derived. |
