    • "Quasiclassical" refers usually to the three-dimensional- quasiclassical theory of superconductivity also called the energy-integrated Green function's theory in which the fast spatial oscillations of the Gorkov Green's functions have been integrated out. The resulting quasiclassical Green's functions depend only on the center-of-mass coordinates. In this framework, the current is expressed as a sum of contributions corresponding to different straight line trajectories labeled by a angle θ. In this article, we discuss the purely one-dimensional case and "quasiclassical" refers to the θ=0 contribution of the full quasiclassical result.

    • note
    • In the superconducting point-contact geometry, two large superconducting reservoirs are connected to a narrow normal metal or ferromagnet. In this situation, the modification of Δ(x) may be neglected whereas for uniform-width junctions the pair potential is suppressed near the FS or NS interfaces. In the point-contact case, the width of the wire connecting the large leads to the thin ferromagnetic strip should have a slow spatial variation in order to avoid backscattering of electrons coming from the superconductors.
