Imprinting Vortices in a Bose-Einstein Condensate using Topological Phases
Abstract
Vortices were imprinted in a Bose-Einstein condensate using topological phases. Sodium condensates held in a Ioffe-Pritchard magnetic trap were transformed from a nonrotating state to one with quantized circulation by adiabatically inverting the magnetic bias field along the trap axis. Using surface wave spectroscopy, the axial angular momentum per particle of the vortex states was found to be consistent with 2ℏ or 4ℏ, depending on the hyperfine state of the condensate.
