Excitation of a Dipole Topological State in a Strongly Coupled Two-Component Bose-Einstein Condensate

March 1, 2000

Author(s)

Juana S. Williams, R Walser, J W. Cooper, Eric A. Cornell, M J. Holland

Two internal hyperfine states of a Bose-Einstein condensate in a dilute magnetically trapped gas of 87Rb atoms are strongly coupled by an external field that drives Rabi oscillations between the internal states. Due to their different magnetic moments and

Watching a Superfluid Untwist Itself: Recurrence of Rabi Oscillations in a Bose-Einstein Condensate

October 1, 1999

M R. Matthews, B P. Anderson, P C. Haljan, D S. Hall, Juana S. Williams, C E. Wieman, Eric A. Cornell

The order parameter of a condensate with two internal states can continuously distort in such a way as to remove twists that have been imposed along its length. We observe this effect experimentally in the collapse and recurrence of Rabi oscillations in a
