Vortex structures of a two-component BEC for large anisotropies
  We calculate the vortex structures of an elongated two-component Bose-Einstein condensate. We study how these structures depend on the intra-component and inter-component interaction strengths. We present analytic and numeric results respectively at weak and strong interactions; finding lattices with different interlocking geometries: triangular, square, rectangular and double-core.
