skyrmion

plural skyrmions

1. solid state physics; string theory; solid state physics; string theorynatural sciencesAny of a particular class of topological soliton that can be used to model certain properties of a nucleon.

   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].
