Sculpting the Vortex State of a Spinor BEC
  We use Raman-detuned laser pulses to achieve spatially-varying control of the amplitude and phase of the spinor order parameter of a Bose-Einstein condensate. We present experimental results confirming precise radial and azimuthal control of amplitude and phase during the creation of vortex-antivortex superposition states.
