Creation of classical and quantum fluxons by a current dipole in a long Josephson junction
Creation of classical and quantum fluxons by a current dipole in a long Josephson junction
We study static and dynamical properties of fluxons in a long annular Josephson junction (JJ) with a current injected at one point and collected back at a close point. Uniformly distributed dc bias current with density $\ensuremath{\gamma}$ is applied too. We demonstrate that, in the limit of the infinitely small …
