主 题：Bose-Einstein condensates spin-orbit coupling vortex-pair states
摘 要：Three types of vortex-pair are identified in two-component Bose-Einstein condensates （BEC） of dif- ferent kinds of spin-orbit coupling. One type holds the two vortices in one component of the two- component condensates. Both the other two types hold a vortex in each component of the two- component condensates, and exhibit meron-pair textures that have either null or unit topological charge, respectively. The cores of the two vortices are connected by a string of the relative phase jump. These vortex pairs can be generated from a vortex-free wave packet by incorporating different non- Abelian gauge field into the BEC. When a Rabi coupling is introduced, the distance between the two cores is effectively controlled by the Rabi coupling strength and a transition of vortex configurations is observed.
