Phys. Rev. Lett. 95, 145301 (2005) [4 pages]Emergence and Decay of Turbulence in Stirred Atomic Bose-Einstein CondensatesReceived 30 May 2005; published 29 September 2005 We show that a “weak” elliptical deformation of an atomic Bose-Einstein condensate rotating at close to the quadrupole instability frequency leads to turbulence with a Kolmogorov energy spectrum. The turbulent state is produced by energy transfer to condensate fragments that are ejected by the quadrupole instability. This energy transfer is driven by breaking the twofold rotational symmetry of the condensate. Subsequently, vortex-sound interactions damp the turbulent state leading to the crystallization of a vortex lattice. © 2005 The American Physical Society URL:
