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