  In an optical trap, the ground state of spin-1 Bosons such as $^{23}$Na,
$^{39}$K, and $^{87}$Rb can be either a ferromagnetic or a "polar" state,
depending on the scattering lengths in different angular momentum channel. The
collective modes of these states have very different spin character and spatial
distributions. While ordinary vortices are stable in the polar state, only
those with unit circulation are stable in the ferromagnetic state. The
ferromagnetic state also has coreless (or Skyrmion) vortices like those of
superfluid $^{3}$He-A. Current estimates of scattering lengths suggest that the
ground states of $^{23}$Na and $^{87}$Rb condensate are a polar state and a
ferromagnetic state respectively.
