where p describes the magnetisation direction in the origin (p=1 (−1) for (=) = ()) and W is the winding number. Considering the same uniform magnetisation, i.e. the same p value, the winding number allows to define the skyrmion (()) with a positive winding number and the antiskyrmion (()) with a negative winding number and thus a topological charge opposite to the one of the skyrmion.
When projected onto a flat surface, an optical vortex looks like a ring of light, with a dark hole in the center. The vortex is given a number, called the topological charge, according to how many twists the light does in one wavelength. The number is always an integer, and can be positive or negative, depending on the direction of the twist.
