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…
The experimental observation of Beliaev damping in a Bose condensed gas
E. Hodby, O. M. Marago', G. Hechenblaikner +1
We report the first experimental observation of Beliaev damping of a collective excitation in a Bose-condensed gas. Beliaev damping is not predicted by the Gross-Pitaevskii equatio…
Bose-Einstein condensation in a stiff TOP trap with adjustable geometry
E. Hodby, G. Hechenblaikner, O. M. Marago' +3
We report on the realisation of a stiff magnetic trap with independently adjustable trap frequencies, and , in the axial and radial directions respectively. This has bee…
Observation of harmonic generation and nonlinear coupling in the collective dynamics of a Bose condensate
G. Hechenblaikner, O. M. Marago', E. Hodby +3
We report the observation of harmonic generation and strong nonlinear coupling of two collective modes of a condensed gas of rubidium atoms. Using a modified TOP trap we changed th…
Observation of the scissors mode and superfluidity of a trapped Bose-Einstein condensed gas
O. M. Marago', S. A. Hopkins, J. Arlt +3
We report the observation of the scissors mode of a Bose-Einstein condensed gas of 87^Rb atoms in a magnetic trap, which gives direct evidence of superfluidity in this system. The…
