Annihilation and recurrence of vortex-antivortex pairs in two-component Bose-Einstein condensates
نویسندگان
چکیده
The annihilation of vortex-antivortex pairs is a key event in two-dimensional Bose-Einstein condensates (BECs). It known that dissipation or catalyst vortex required for the one-component BECs. We numerically confirmed two-component BECs can be annihilated even without any vortices when intercomponent interaction strong. In addition, pair recreated alternately two components under certain conditions, which we call recurrence.

Vortex lattice locking in rotating two-component Bose–Einstein condensates
The vortex density of a rotating superfluid, divided by its particle mass, dictates the superfluid’s angular velocity through the Feynman relation. To find how the Feynman relation applies to superfluid mixtures, we investigate a rotating two-component Bose–Einstein condensate, composed of bosons with different masses. We find that in the case of sufficiently strong interspecies attraction, the...
متن کاملVortex molecules in coherently coupled two-component Bose-Einstein condensates.
A vortex molecule is predicted in rotating two-component Bose-Einstein condensates whose internal hyperfine states are coupled coherently by an external field. A vortex in one component and one in the other are connected by a domain wall of the relative phase, constituting a "vortex molecule," which features a nonaxisymmetric (pseudo)spin texture with a pair of merons. The binding mechanism of ...
متن کاملVortex phase diagram in rotating two-component Bose-Einstein condensates.
We investigate the structure of vortex states in rotating two-component Bose-Einstein condensates with equal intracomponent but varying intercomponent-coupling constants. A phase diagram in the intercomponent-coupling versus rotation-frequency plane reveals rich equilibrium structures of vortex states. As the ratio of intercomponent to intracomponent couplings increases, the interlocked vortex ...
متن کاملTwo-component Bose-Einstein Condensates
This talk is about two-component Bose-Einstein condensate in a harmonic trap. The aim is to describe the shape and the spatial configuration of the ground state pairs. We will show links between our model and other mathematical problems : optimal partition problems and the Cahn-Hilliard model for phase transition. These links appear in our model in the limit when intercomponent particle interac...
متن کاملVortex lattice formation in Bose-Einstein condensates.
We show that the formation of a vortex lattice in a weakly interacting Bose condensed gas can be modeled with the nonlinear Schrödinger equation for both T=0 and finite temperatures without the need for an explicit damping term. Applying a weak rotating anisotropic harmonic potential, we find numerically that the turbulent dynamics of the field produces an effective dissipation of the vortex mo...
