Vortex Nucleation and Array Formation in a Rotating Bose-Einstein Condensate
نویسندگان
چکیده
We study the dynamics of vortex lattice formation of a rotating trapped Bose-Einstein condensate by numerically solving the two-dimensional GrossPitaevskii equation, and find that the condensate undergoes elliptic deformation, followed by unstable surface-mode excitations before forming a quantized vortex lattice. The dependence of the number of vortices on the rotation frequency is obtained. PACS numbers: 03.75.Fi, 67.40.Db.

Bose-Einstein condensation from a rotating thermal cloud: Vortex nucleation and lattice formation
We develop a stochastic Gross-Pitaveskii theory suitable for the study of Bose-Einstein condensation in a rotating dilute Bose gas. The theory is used to model the dynamical and equilibrium properties of a rapidly rotating Bose gas quenched through the critical point for condensation, as in the experiment of Haljan et al. #Phys. Rev. Lett. 87, 210403 !2001"$. In contrast to stirring a vortex-fr...
متن کاملFormation of Quantized Vortices in a Gaseous Bose-einstein Condensate
Using a focused laser beam we stir a Bose-Einstein condensate confined in a magnetic trap. When the stirring frequency lies near the transverse quadrupolar mode resonance we observe the nucleation of vortices. When several vortices are nucleated, they arrange themselves in regular Abrikosov arrays, and in the limit of large quantum number the lattice structure is shown to produce a quantum velo...

متن کاملSymmetry Breaking in Bose-Einstein Condensates
A gaseous Bose-Einstein condensate (BEC) offers an ideal testing ground for studying symmetry breaking, because a trapped BEC system is in a mesoscopic regime, and situations exist under which symmetry breaking may or may not occur. Investigating this problem can explain why mean-field theories have been so successful in elucidating gaseous BEC systems and when manybody effects play a significa...
متن کاملDynamical thermalization and vortex formation in stirred two-dimensional Bose-Einstein condensates
We present a quantum-mechanical treatment of the mechanical stirring of Bose-Einstein condensates using classical field techniques. In our approach the condensate and excited modes are described using a Hamiltonian classical field method in which the atom number and rotating frame energy are strictly conserved. We simulate a T=0 quasi-two-dimensional condensate perturbed by a rotating anisotrop...
