In the absence of SOC, the periodic magnetic field induces vortex-anti-vortex structures in the $\\ket{F=1, m_F=\\pm1}$ condensates at saddle-points, such that the net topological charge remains zero. The introduction of Rashba SOC breaks the system's symmetry, leading to non-conservation of overall angular momentum in the spin-1 condensate. This anisotropy results in the emergence of certain skyrmion spin textures.
