Meaning of topological soliton | Babel Free

Definitions

A type of soliton that forms the transition between two adjoining structures or spaces which are "out of phase" in such a way that the transition cannot be seamless.

Examples

“One of the simplest and most commonplace examples of a topological soliton occurs in old-fashioned coiled telephone handset cords, which are usually coiled clockwise. Years of picking up the handset can end⟳ up coiling parts of the cord in the opposite counterclockwise direction, and when this happens there will be a distinctive larger loop that separates the two directions of coiling. This odd looking transition loop, which is neither clockwise nor counterclockwise, is an excellent example of a topological soliton.^([Wikipedia])”

“A dynamic theory is derived for the motion of a Bloch point⟳, i.e., a point⟳ topological soliton which is homotopically equivalent to a "hedgehog," along a Bloch line in a ferromagnet.”
