===Etymology===
{{blend|en|Skyrme|fermion}}, after British [[physicist]] {{w|Tony Skyrme}} (1922–1987), who proposed the mathematical structure as a model of the [[nucleon]] in 1961.

|passage=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].}}
