Experimental observation of a superfluid gyroscope in a dilute Bose-Einstein condensate.

Phys Rev Lett 91:9 (2003) 090403

Authors:

E Hodby, SA Hopkins, G Hechenblaikner, NL Smith, CJ Foot

Abstract:

We have observed a three-dimensional gyroscopic effect associated with a vortex in a dilute Bose-Einstein condensed gas. A condensate with a vortex possesses a single quantum of circulation, and this causes the plane of oscillation of the scissors mode to precess around the vortex line. We have measured the precession rate of the scissors oscillation. From this we deduced the angular momentum associated with the vortex line and found a value close to Planck's over 2pi per particle, as predicted for a superfluid.

The evaporative cooling of a gas of caesium atoms in the hydrodynamic regime

Journal of Physics B Atomic Molecular and Optical Physics 36:16 (2003) 3533-3540

Authors:

ZY Ma, AM Thomas, CJ Foot, SL Cornish

Abstract:

We study the efficiency of evaporative cooling of a trapped gas of caesium atoms in the hydrodynamic regime by the numerical solution of classical kinetic theory equations. The results of the numerical simulation are compared to our experimental observations of evaporative cooling of magnetically trapped 133Cs atoms in the F = 3, MF = -3 state. The simulation accurately reproduces our experimental performance and indicates that the reduction in cooling efficiency as the gas enters the hydrodynamic regime is the main obstacle to the realization of Bose-Einstein condensation (BEC) in this state. The simulation is used to explore alternative routes to BEC.
