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

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.

## Abstract The experimental imaging of microscopic currents in two‐dimensional electron gas based systems has been recently realized exploiting an ingenious use of scanning microscope tips. By means of the Keldysh Green's function formalism in a tight‐binding framework, I study the electron transp
