Abstract:
Relation between Yang-Mills theory and Skyrme model is discussed. We consider rational map approach and the structure of multisoliton solutions of the Skyrme model and the Faddeev-Skyrme model. The properties of triply periodic Skyrme crystals in the generalized Skyrme model are investigated. Various scenarios of phase transitions from the low-density phase to the high-density phase are examined for different choices of the parameters of the model. Considering the near-Bogomolny-Prasad-Sommerfeld submodel, we found that there are indications of the phase transition from a low-density quasi-liquid phase to the high-density symmetric phase of the Skyrmionic matter.
