We theoretically generalize a systematic language to describe the phase-imprinting technique to investigate the dynamical generation of solitons in a one-dimensional Raman-type spin-orbit-coupled Fermi superfluid. We check our method with the simulation of time-dependent Bogoliubov–de Gennes equations and find that our method not only can generate stable dark and even gray solitons in a conventional Fermi superfluid by controlling the transferred phase jump but also is feasible to create a stable dark soliton in both BCS and topological states of a spin-orbit-coupled Fermi superfluid. We also discuss the physical implication of our method.

具有和不具有自旋轨道耦合的一维费米超流体中孤子的动力学生成

我们在理论上概括了一种系统语言来描述相位印记技术，以研究一维拉曼型自旋轨道耦合费米超流体中孤子的动态产生。我们通过对瞬态 Bogoliubov-de Gennes 方程的模拟来检查我们的方法，发现我们的方法不仅可以通过控制转移的相位跳跃在传统的费米超流体中生成稳定的暗甚至灰色孤子，而且还可以创建稳定的自旋轨道耦合费米超流体的 BCS 和拓扑状态中的暗孤子。我们还讨论了我们方法的物理含义。
