Abstract:Skyrmions are topologically protected field configurations characterised by a topological index, the skyrmion number. Optical skyrmions are ideally suited to investigate topological structures due to the ease of generating arbitrary light fields, and the freedom from energy constraints encountered by, for example, magnetic skyrmions. Building on our previous work of a topologically defined skyrmion number, 1 here we demonstrate the conservation of the skyrmion number of hedgehog skyrmions and bimerons under pr… Show more
