Phys. Rev. A 66, 013616 (2002) [5 pages]Vortex-vortex interaction in two-component Bose-Einstein condensatesReceived 7 November 2001; published 30 July 2002 The vortex-vortex interaction in two-component Bose-Einstein condensates is shown to present characteristic effects not possible in single-component condensates. In particular, vortices in different components undergo separate, but concentric, orbits for both the same and opposite circulation. In addition, contrary to the well-known behavior in single-component condensates, vortices with the same circulation created in the less dense component merge in the presence of dissipation, allowing for the creation of metastable vortices with more than one quantum of circulation. © 2002 The American Physical Society URL:
