论文摘要
出现在旋转轨道耦合的玻璃纤维凝结物（SOC-BEC）基底状态下的固定明亮孤子。我们考虑在线性和非线性光学栅栏中进行SOC-BEC，并研究它们对物质波明亮的孤子的影响，并发现可以明智地操纵非线性晶格或原子散射长度的参数，以控制对Soliton节点的有用控制。可以看出，与较少数量的节点相比，具有大量节点的孤子的稳定性较低。我们推断，合成的自旋轨道耦合会在普通物质波孤子中引起不稳定性。
The stationary bright solitons that appear in the ground state of the spin-orbit coupled Bose-Einstein condensate (SOC-BEC) exhibit nodes. We consider SOC-BEC in combined linear and nonlinear optical lattices and study their effects on the matter-wave bright soliton and find that the parameters of the nonlinear lattice or atomic scattering length can be judiciously manipulated to have useful control over the nodes of the soliton. It is seen that the soliton with large number of nodes is less stable compared to one having fewer number of nodes. We infer that that the synthetic spin-orbit coupling induces instability in the ordinary matter-wave soliton.
