Oscillating Solitons and AC Josephson Effect in Ferromagnetic Bose-Bose Mixtures

  title={Oscillating Solitons and AC Josephson Effect in Ferromagnetic Bose-Bose Mixtures},
  author={Sebastiano Bresolin and Arko Roy and G. Ferrari and Alessio Recati and Nicolas Pavloff},
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…

Propagating Ferrodark Solitons in a Superfluid: Exact Solutions and Anomalous Dynamics.

Exact propagating topological solitons are found in the easy-plane phase of ferromagnetic spin-1 Bose-Einstein condensates, manifesting themselves as kinks in the transverse magnetization.

Solution of the Riemann problem for polarization waves in a two-component Bose-Einstein condensate.

The situation where the dynamics can be reduced to the consideration of a single polarization mode obeying a system of equations equivalent to the Landau-Lifshitz equation for an easy-plane ferromagnet is considered.

The DC Josephson effect is the flow of supercurrent across a weak link between two superconductors with different values of their order parameters, the phase. We formulate this notion for any kind

Observation of Massless and Massive Collective Excitations with Faraday Patterns in a Two-Component Superfluid.

We report on the experimental measurement of the dispersion relation of the density and spin collective excitation modes in an elongated two-component superfluid of ultracold bosonic atoms. Our

Critical Energy Dissipation in a Binary Superfluid Gas by a Moving Magnetic Obstacle.

Analysis of critical energy dissipation in an atomic superfluid gas with two symmetric spin components by an oscillating magnetic obstacle reveals the characteristic evolution of critical dissipative dynamics from spin-wave emission to HQV shedding.

Magnetic solitons in an immiscible two-component Bose-Einstein condensate

We investigate magnetic solitons in an immiscible binary Bose-Einstein condensate (BEC), where the intraspecies interactions are slightly weaker than the interspecies interactions. While their

A rich variety of physical effects in the spin dynamics arises at the interface (domain wall) between different magnetic materials. Engineered physical systems based on magnetic interlaced structures

Observation of Magnetic Solitons in Two-Component Bose-Einstein Condensates.

The dynamics of spin solitary waves (magnetic solitons) in a harmonically trapped, binary superfluid mixture is experimentally investigated and the in situ density of each pseudospin component and their relative local phase is measured via an interferometric technique.

Spin soliton with a negative-positive mass transition

We obtain a striking spin soliton in a two-component Bose-Einstein condensate and investigate its motions in the presence of a constant force. The initially static spin soliton first moves in a
