A method to create disordered vortex arrays in atomic Bose-Einstein condensates
arXiv:0808.0636 · doi:10.1139/P09-069
Abstract
We suggest a method to create turbulence in a trapped atomic Bose-Einstein condensate (BEC). By replacing in the upper half part of our box the wave function, Psi, with its complex conjugate, Psi^{*}, new negative vortices are introduced into the system. The simulations are performed by solving the two-dimensional Gross-Pitaevskii equation (2D GPE). We study the successive dynamics of the wave function by monitoring the evolution of density and phase profile.
