Vortex knots in a Bose-Einstein condensate.
We present a method for numerically building a vortex knot state in the superfluid wave function of a Bose-Einstein condensate. We integrate in time the governing Gross-Pitaevskii equation to determine evolution and shape preservation of the two (topologically) simplest vortex knots which can be wrapped over a torus. We find that the velocity of a vortex knot depends on the ratio of poloidal an...
متن کاملVortex motion in trapped Bose–Einstein condensate
We have studied the motion of a vortex-antivortex pair together with a single vortex in trapped Bose-Einstein condensate (BEC) by numerically solving the twodimensional Gross-Pitaevskii equation, and found that the path of the vortices depends on the initial separation distance and dissipation. This motion was periodic and it was found that sound waves appear due to the cyclical movement, whose...
متن کاملEnergetically stable particlelike skyrmions in a trapped Bose-Einstein condensate.
We numerically show that a topologically nontrivial 3D Skyrmion can be energetically stable in a trapped two-component atomic Bose-Einstein condensate, for the parameters of 87Rb condensate experiments. The separate conservation of the two atomic species can stabilize the Skyrmion against shrinking to zero size, while drift of the Skyrmion due to the trap-induced density gradient can be prevent...
متن کاملKnots in a spinor Bose-Einstein condensate.
We show that knots of spin textures can be created in the polar phase of a spin-1 Bose-Einstein condensate, and discuss experimental schemes for their generation and probe, together with their lifetime.
متن کاملA vortex dipole in a trapped two-dimensional Bose-Einstein condensate
We study the conservative dynamics and stationary configurations of a vortex-antivortex pair in a harmonically trapped two-dimensional Bose-Einstein condensate. We establish the conceptual framework for understanding the stationary states and the topological defect trajectories, through considerations of different mechanisms of vortex motion and the bifurcation of soliton-like stationary soluti...
