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…
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.…
