摘要：
Recently, coupled systems of nonlinear Schrodinger equations have been used extensively to describe Bose-Einstein condensates. In this paper, we study the structure of Vortices of the coupled nonlinear equations for two-component Bose-Einstein condensates (BEC) in a three-dimensional space. We show that vortices is 1-rectifiable set, and give its mean curvature. In particular, we show that large interspecies scattering length causes vortices for two-component BEC. (C) 2008 Elsevier Inc.
