Query: Variation of the spin textures of 2-species spin-1 condensates studied
  beyond the single spatial mode approximation and the experimental
  identification of these textures   Based on the numerical solutions of the coupled Gross-Pitaevskii equations,
the spin-textures of a Bose-Einstein condensate with two kinds of spin-1 atoms
have been studied. Besides, the probability densities of an atom in spin
component $\mu$ and of two correlated atoms one in $\mu$ and one in $\nu$ have
been calculated. By an analysis of the densities, four types of texture have
been found. (i) Both species are in polar phase. (ii) Both species are in
ferromagnetic (f) phase with all the spins lying along a direction. (iii) Both
species are in f phase but the spins of different species are lying along
opposite directions. (iv) One species in f phase, one species in quasi-f phase
(where the spins are divided into two groups lying along opposite directions).
This finding simplifies the previous classification. Moreover, we found that
the variation and transition of the spin-textures can be sensitively reflected
by these probability densities. Therefore, the theoretical and experimental
studies on these densities provide a way to discriminate the spin-textures
and/or to determine the parameters (say, the strengths of interaction)
involved.
