Transition to the giant vortex state for a Bose-Einstein condensate in a rotating anharmonic trap
We study the fast rotation limit for a Bose-Einstein condensate in a quadratic plus quartic confining potential within the framework of the two dimensional Gross-Pitaevskii energy functional. As the rotation speed tends to infinity, the condensate undergoes a phase transition to the socalled giant vortex state: an annulus with pure irrotational flow encircling a central low-density hole around ...
متن کاملDynamics of a Bose-einstein Condensate in an Anharmonic Trap
We present a theoretical model to describe the dynamics of a Bose-Einstein condensates in an-harmonic trapping potentials. The center of mass motion is separated from the internal condensate dynamics and the problem is reduced to the well known scaling solutions for the Thomas-Fermi radii. We discuss the validity of this approach and analyze the model for an anharmonic waveguide geometry which ...
متن کاملVortex 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 کاملThe giant vortex state for a Bose-Einstein condensate in a rotating anharmonic trap : extreme rotation regimes
We study the fast rotation limit for a Bose-Einstein condensate in a quadratic plus quartic confining potential within the framework of the two dimensional Gross-Pitaevskii energy functional. As the rotation speed tends to infinity with a proper scaling of the other parameters in the model, a linear limit problem appears for which we are able to derive precise energy estimates. We prove that th...
متن کاملObservation of vortex dipoles in an oblate Bose-Einstein condensate.
We report experimental observations and numerical simulations of the formation, dynamics, and lifetimes of single and multiply charged quantized vortex dipoles in highly oblate dilute-gas Bose-Einstein condensates (BECs). We nucleate pairs of vortices of opposite charge (vortex dipoles) by forcing superfluid flow around a repulsive Gaussian obstacle within the BEC. By controlling the flow veloc...
