Production Efficiency of Ultracold Feshbach Molecules in Bosonic and Fermionic Systems
E. Hodby, S. T. Thompson, C. A. Regal +5
We investigate the production efficiency of ultracold molecules in bosonic Rb and fermionic K when the magnetic field is swept across a Feshbach resonance. For adiaba…
The Experimental Observation of a Superfluid Gyroscope in a dilute Bose Condensed Gas
E. Hodby, S. A. Hopkins, G. Hechenblaikner +2
We have observed a superfluid gyroscope effect in a dilute gas Bose-Einstein condensate. A condensate with a vortex possesses a single quantum of angular momentum and this causes t…
The Moment of Inertia and the Scissors Mode of a Bose-condensed Gas
O. M. Marago', G. Hechenblaikner, E. Hodby +2
We relate the frequency of the scissors mode to the moment of inertia of a trapped Bose gas at finite temperature in a semi-classical approximation. We apply these theoretical resu…
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…
