Outline
  • Assumptions
  • Creating vortices via phase imprinting
  • Creating BEC cocktails via trap shaking
  • Two component BEC in random Raman field
  • Breaking the continuous symmetry
  • Disorder induced order
  • Control of the relative phase

4
Assumptions
  • Assumption 1 we have a magnetic trap
  • Assumption II we have some, but not too much
    of optical access.
  • Assumptopn III we have control over magnetic
    fields
  • Assumption IV we have access to two components
  • (pseudo-spin ½)
  • Assumption V BEC to the future will be more
    possibilities
