Scientists have demonstrated how to structure light such that its polarization behaves like a collective of spins in a ferromagnet forming half-skyrmions (also known as merons). To achieve this, the light was trapped in a thin liquid crystal layer between two nearly perfect mirrors. Skyrmions, in general, are found, e.g., as elementary excitations of magnetization in a two-dimensional…
