Description
Superfluids made from atoms with spins can form many
different types of vortices, unlike superfluid helium, which
can support only ordinary vortices. Ordinary vortices are
surrounded by a stable flow of atoms; the additional types
of vortices also are wreathed by spin patterns. The more
symmetry the condensate has, the greater the variety of
vortices.
An imperfection in the symmetry causes some of types
vortices to form molecules, according to the laws of
``vortex chemistry." I will explain two applications: one
application predict metastable vortex molecules; the other
predicts Newtonian physics (instead of Magnus force
dynamics) for a spin-current vortex.
