Abstract(in Japanese) (See Japanese page)
Abstract(in English) We notice the motion of quasiparticles which obey Bogoliubov-de Gennes equation (BdGE) and calculate superconducting current in SNS and SNSNS junctions (S:superconductor, N:normal conductor). This current can be obtained from the probability amplitudes of the Andreev reflection which are obtained by solving the BdGE. The Josephson effect is a phenomenon observed both in tunnel junctions and weak-links, so, we calculate the Josephson current in each case.
