Description
The meson condensed phase is an interesting portal on the properties of QCD in a regime in which various methods, including lattice QCD, are reliable.
We discuss inhomogeneous topologically nontrivial configurations of the pion fields
in the framework of chiral perturbation theory.
Solitons characterized by a nonvanishing topological charge naturally emerge. These states that can be identified with baryons surrounded by a bath of pions, meaning that the system has an effective nonvanishing baryonic density.
