论文摘要
Spin-1自旋 - 摩托耦合旋转纺纱型玻璃晶冷凝物已在实验中实现。我们研究了具有光学晶格的实验可实现的系统，研究了旋转轨道耦合的旋转缝隙。自旋轨道耦合的自旋依赖性均衡对称性在间隙孤子的性质中起重要作用。发现了两个具有相反自旋依赖奇偶校验的孤子家族。使用近似模型通过用谐波陷阱代替光学晶格，我们证明了这两个家族的物理起源。对于大型的负二次Zeeman偏移，我们还找到了一种缝隙孤子，它们会自发地破坏由于铁磁纺纱镜的相互作用而使自旋依赖性的平等对称性。
Spin-1 spin-orbit-coupled spinor Bose-Einstein condensates have been realized in experiment. We study spin-orbit-coupled spinor gap solitons in this experimentally realizable system with an optical lattice. The spin-dependent parity symmetry of the spin-orbit coupling plays an important role in properties of gap solitons. Two families of solitons with opposite spin-dependent parity are found. Using an approximating model by replacing the optical lattice with a Harmonic trap, we demonstrate the physical origination of these two families. For a large negative quadratic Zeeman shift, we also find a type of gap solitons that spontaneously breaks the spin-dependent parity symmetry due to the ferromagnetic spinor interactions.
