dc.description.abstract
We analyze the existence of localized finite energy topological excitations on top of the perturbative pion vacuum within the Skyrme model at finite isospin chemical potential and finite pion mass. We show that there is a critical isospin chemical potential mu^c_I above which such solutions cease to exist. We find that mu^c_I is closely related to the value of the pion mass. In particular, for vanishing pion mass we obtain mu^c_I = 0 in contradiction with some results recently reported in the literature. We also find that below mu^c_I the skyrmion mass and baryon radius show, at least for the case of the hedgehog ansatz, only a mild dependence on the isospin chemical potential.
