摘要：

The amplitude of the Coulomb blockade oscillations is calculated for a single-mode Josephson junction with arbitrary electron transparency D. It is shown that a mechanism related to chiral anomaly completely suppresses the Coulomb blockade in ballistic junctions with D = 1. At finite reflection probability, the suppression process is described quantitatively in terms of the Landau-Zener transition. [S0031-9007(99)09032-8].
