text: The study of spinor condensates was initiated in 1998 by experimental groups at JILA 
  and MIT.  These experiments utilised
  Na and Rb atoms, respectively.
  In contrast to most prior experiments on ultracold gases, these experiments utilised a purely
  optical trap, which is spin-insensitive.  Shortly thereafter, theoretical work appeared
  which described the possible mean-field phases of spin-one spinor condensates.
