Phys. Rev. Lett. 88, 010405 (2001) [4 pages]Vortex Nucleation in Bose-Einstein Condensates in an Oblate, Purely Magnetic PotentialReceived 13 June 2001; published 19 December 2001 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 TOP trap to create an elliptical potential that rotates in the radial plane. This enabled us to study the conditions for vortex nucleation over a wide range of eccentricities and rotation rates. © 2002 The American Physical Society URL:
