Topological solitons can be found in many places and at many different length scales. For example, they take the form of kinks in coiled telephone cords and large molecules such as proteins.

Solitons are pulses of light that maintain their temporal shape during propagation by precisely balancing two opposing effects — nonlinear Kerr-effect self-phase modulation and linear dispersion ...

Solitons are waves with just a single crest. They result when a wave’s natural tendency to spread as it propagates is cancelled out by an inherently nonlinear phenomenon known as self-focusing.
