论文摘要
我们引入了Bose-Einstein冷凝物（BEC） - skyrme模型的变化，其可能会引起两个物理涡流字符串的可能性可混杂的BEC。在每个拓扑领域的基础状态下，由于最近制定的定理，涡流恰好链接到$ b $ times，而$ b $是解决方案的重子。该模型还具有亚稳态状态，其中涡流是退化的，并且不将重子数字解释为涡流的链接数。
We introduce a variation of the Bose-Einstein condensate(BEC)-Skyrme model, with an altered potential for miscible BECs that gives rise to two physical vortex strings. In the ground state of each topological sector, the vortices are linked exactly $B$ times, due to a recently formulated theorem, with $B$ being the baryon number of the solution. The model also possesses metastable states, where the vortices are degenerate and do not lend the interpretation of the baryon number as the linking number of the vortices.
