The scientists have demonstrated how to structure light such that its polarization behaves like a collective of spins in a ferromagnet forming half-skyrmion (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 ferromagnet but do not naturally appear in electromagnetic (light) fields.
One of the key concepts in physics, and science overall is the notion of a field which can describe the spatial distribution of a physical quantity. For instance, a weather map shows the distributions of temperature and pressure (these are known as scalar fields), as well as the wind speed and direction (known as a vector field).
