Oscillating Solitons and AC Josephson Effect in Ferromagnetic Bose-Bose Mixtures
arXiv:2209.11536 · doi:10.1103/PhysRevLett.130.220403
Abstract
Close to the demixing transition, the degree of freedom associated to relative density fluctuations of a two-component Bose-Einstein condensate is described by a non-dissipative Landau-Lifshitz equation. In the quasi one-dimensional weakly immiscible case, this mapping surprisingly predicts that a dark-bright soliton should oscillate when subject to a constant force favoring separation of the two components. We propose a realistic experimental implementation of this phenomenon which we interpret as a spin-Josephson effect in the presence of a movable barrier.
