In contrast to one-component Bose-Einstein condensate
case, the vortices in two-component condensate
can have various complicated structures. The vortices in a
space-homogeneous Bose-Einstein condensate have been
studied in this paper. It is shown that the vortex structure
is described by three dimensionless parameters. This is totally
different from the usual one-component condensate
case,where an isolated vortex is described by a parameterless
dimensionless equation. The two-component vortex
structure strongly depends on the sign of “interaction”
constant of the components. A few types of vortices with
different qualitative structure are explored. We show that
the “super-density vortices” can exist, when the “interaction”
constant is positive. The “super-density vortices”
have the near-axis density greater than the equilibrium
density of a homogeneous space Bose-Einstein condensate.
We also show that the vortices with opposite direction
of the condensate component rotation near the axis
and far off the axis can exist.
