skyrmion

1. (physics, solid state physics, string theory) Any of a particular class of topological soliton that can be used to model certain properties of a nucleon.Examples: "No conclusive results are available yet; the hope is that the skyrmion would be stabilized at R#92;approx#92;lambda#95;c, where the gradient expansion breaks down and yet the skyrmion may still carry the quark quantum numbers."; "The properties of nuclear matter at high densities have been investigated in many ways. Castillejo et al. studied Skyrmion matter by placing SU(2) hedgehog Skyrmions on a lattice and show that the deconfinement phase transition and the chiral symmetry restoration occur above a critical density [11]."

2. (physics, solid state physics) A type of topological soliton that occurs in magnetic materials and magnetic thin films.Synonyms: magnetic skyrmion
