Nonlocal mixing of supercurrents in Josephson ballistic point contact
arXiv:cond-mat/0304317 · doi:10.1103/PhysRevB.67.172504
Abstract
We study coherent current states in the mesoscopic superconducting weak link simultaneously subjected to the order parameter phase difference on the contact and to the tangential to the junction interface superfluid velocity in the banks. The Josephson current-phase relation controlled by the external transport current is obtained. At phase difference close to pi the nonlocal nature of the Josephson phase-dependent current results in the appearance of two vortexlike states in the vicinity of the contact.
