We study the ground-state phases of Rabi-coupled two-component Bose-Einstein condensates with rotation and spatially modulated nonlinear spin-orbit coupling. The spin-orbit coupling and Rabi coupling play important roles on the ground-state phases with the fixed rotation, however, they have the opposite effects on the generation of vortex. When the system without Rabi coupling, spin-orbit coupling can improve the generation of vortex. The vortex chain with regular pattern appears with strong spin-orbit coupling. Considering the Rabi coupling, the number of vortices is inhibited by the Rabi coupling with the fixed spin-orbit coupling and rotation strengths. The ground-state phase diagram spanned by the SOC strength and Rabi coupling with rotation is presented, the non-vortex phase, single-vortex phase and multi-vortex phase are classified. The spin textures of the ground-state phases are also discussed.

我们研究了具有旋转和空间调制非线性自旋轨道耦合的 Rabi 耦合双组分玻色-爱因斯坦凝聚的基态相位。自旋轨道耦合和 Rabi 耦合对固定旋转的基态相位起重要作用，但它们对涡旋的产生具有相反的影响。当系统没有Rabi耦合时，自旋轨道耦合可以改善涡流的产生。出现规律图案的涡链，具有较强的自旋轨道耦合。考虑到 Rabi 耦合，涡旋的数量受到具有固定自旋轨道耦合和旋转强度的 Rabi 耦合的抑制。给出了由SOC强度和Rabi与旋转耦合形成的基态相图，分为非涡旋相位、单涡旋相位和多涡旋相位。
