Coulomb blockade in superconducting quantum point contacts
D. V. Averin
Abstract
Amplitude of the Coulomb blockade oscillations is calculated for a single-mode Josephson junction with arbitrary electron transparency D. It is shown that the Coulomb blockade is suppressed in ballistic junctions with D 1. The suppression is described quantitatively as the Landau-Zener transition in imaginary time.
