Optical skyrmions: novel topological fields of light

Abstract: Skyrmions are topologically protected field configurations that have been observed in condensed matter systems, chiral magnetic systems and nematic liquid crystals, and most recently in optics. Since their initial conception in 2018, optical skyrmions have attracted considerable attention due to their highly reconfigurable generation. Unlike their magnetic counterparts, optical skyrmions are free from energy constraints and therefore allow the investigation of topological stability in its purest form. In this talk, I will provide a definition of optical skyrmions based on rational maps, I will show how we generate such beams in the laboratory and I will demonstrate how we can characterize them using topological considerations.
