论文摘要
从理论上讲，我们在零温度下在二次zeeman效应的情况下，在旋转1玻色凝结的极性相位的固定孤子的结构。通过在极相的定义范围内找到最小孤子能的状态来映射此类孤子的相图。根据核心中的数量和自旋密度，将各州分为正常，抗铁磁，断裂轴对称性和铁磁相。在平均场理论中证明了不同孤子和相关连续转变的临界行为之间的相变顺序。
We theoretically study the structure of a stationary soliton in the polar phase of spin-1 Bose--Einstein condensate in the presence of quadratic Zeeman effect at zero temperature. The phase diagram of such solitons is mapped out by finding the states of minimal soliton energy in the defining range of polar phase. The states are assorted into normal, anti-ferromagnetic, broken-axisymmetry, and ferromagnetic phases according to the number and spin densities in the core. The order of phase transitions between different solitons and the critical behaviour of relevant continuous transitions are proved within the mean-field theory.
