Abstract

We apply the method of a two-point quasiclassical Green’s function to geometries where the trajectories include intefering paths and loops. For a system of two superconducting layers separated by a partially transparent interface, corrections to the quasiclassical solutions for the Green’s function are explicitly found as well as the deviation from the normalization condition.
