Vortices in ultracold dilute atomic gases have generally been associated with external
rotation, with many beautiful experimental observations. The transformation to a rotating frame of
reference involves a vector gauge field
A = M Ω x r , leading to a uniform effective magnetic field.
Recently, other synthetic gauge fields have been created, leading to many dramatic new phenomena
such as vortices in nonrotating condensates  and effective spin-orbit coupling . The latter
possibility raises many issues about the structure and dynamics of a vortex in a spin-orbit system. I
report on progress in understanding these questions.
