Observation of vortex nucleation in a rotating two-dimensional lattice of Bose-Einstein condensates
R. A. Williams, S. Al-Assam, C. J. Foot
We report the observation of vortex nucleation in a rotating optical lattice. A 87Rb Bose-Einstein condensate was loaded into a static two-dimensional lattice and the rotation freq…
Vortex nucleation in Bose-Einstein condensates in an oblate, purely magnetic potential
E. Hodby, G. Hechenblaikner, S. A. Hopkins +2
We have investigated the formation of vortices by rotating the purely magnetic potential confining a Bose-Einstein condensate. We modified the bias field of an axially symmetric TO…
Direct observation of irrotational flow and evidence of superfluidity in a rotating Bose-Einstein condensate
G. Hechenblaikner, E. Hodby, S. A. Hopkins +2
We observed the expansion of vortex-free Bose-condensates after their sudden release from a slowly rotating anisotropic trap. Our results show clear experimental evidence of the ir…
Calculation of mode coupling for quadrupole excitations in a Bose-Einstein condensate
G. Hechenblaikner, S. A. Morgan, E. Hodby +2
In this paper we give a theoretical description of resonant coupling between two collective excitations of a Bose condensed gas (BEC) on, or close, to a second harmonic resonance.…
