AI 中文摘要
磁斯格明子（MSks）与光学斯格明子（OSks）分别体现了物质与光中的拓扑特性。本研究探究单个磁斯格明子与光学斯格明子束之间的相互作用，识别出三种不同的非线性动力学模式：旋转、跳跃与次摆线运动。通过将光学驱动力分解为梯度、轨道角动量及自旋角动量贡献，明确其分别起径向约束、方位角漂移与进动调制的作用。跳跃运动源于光学斯格明子束的方位角不对称，呈现出由磁斯格明子与光学斯格明子间磁化-偏振耦合产生的空间选择性；在三维空间中，该耦合获得依赖于传播的相位，由微分古伊相位主导，形成z不对称的跳跃轨迹。这些结果在统一框架内连接了拓扑粒子与拓扑场，为光磁控制提供了 helicity 选择性及相位可编程的途径。
英文摘要
Magnetic skyrmions (MSks) and optical skyrmions (OSks) embody topology in matter and in light, respectively. Here we investigate the interaction between a single MSk and an OSk beam. Three distinct nonlinear dynamical modes are identified: rotation, skipping, and trochoidal motion. By decomposing the optical driving force into gradient, orbital-angular-momentum, and spin-angular-momentum contributions, we clarify their respective roles of radial confinement, azimuthal drift, and precessional modulation. The skipping motion arises from the azimuthal asymmetry of the OSk beam and exhibits spatial selectivity originating from the magnetization-polarization coupling between the MSk and OSk. In three dimensions, the coupling acquires a propagation-dependent phase dominated by the differential Gouy phase, which yields $z$-asymmetric skipping trajectories. These results bridge topological particles and topological fields within a unified framework, offering helicity-selective and phase-programmable routes to optomagnonic control.
