Amplitude of the Coulomb blockade oscillations is calculated for a single-mode Josephson junction with large electron transparency D. It is shown that the Coulomb blockade is suppressed as D + 1. The suppression is described quantitatively in terms of the Landau-Zener transition in imaginary time.
The dc Josephson effect in a superconducting quantum point contact, where supercurrent flows through a small number of channels, is reviewed. The central role of Andreev levels is emphasized which carry the whole supercurrent in short symmetric Josephson junctions including tunnel junctions. A simpl
