a, b Superposition of the even and odd molecules at the \(K\) valley. For the scalar pressure field superposition in a, experimental data in Figs. 3d and 4d are used, while for the spin vector field superposition in b, the data in Figs. 3c and 4c are used. The results demonstrate the decoupling of the vortex/skyrmion pairs, with their individual topological properties isolated at different sublattices. This is corroborated by the quantized skyrmion numbers \({n}_{{sk}}\) and the stereographic projections of the spin vector field (within the dashed circular regions). c, d The same as a, b, but for the \({K}^{{\prime} }\)-valley decomposition. Parallel analysis reveals time-reversed configurations.
