  The Chiral Dilaton Model, where baryons arise as non-topological solitons
built from the interaction of quarks and chiral mesons, shows in the high
density low temperature regime a two phase scenario in the nuclear matter phase
diagram. Dense soliton matter described by the Wigner-Seitz approximation
generates a periodic potential in terms of the sigma and pion fields that leads
to the formation of a band structure. The analysis up to three times nuclear
matter density shows that soliton matter undergoes two separate phase
transitions: a delocalization of the baryon number density leading to $B=1/2$
structures, as in skyrmion matter, at moderate densities, and quark
deconfinement at larger densities. This description fits well into the
so-called quarkyonic phase where, before deconfinement, nuclear matter should
undergo structural changes involving the restoration of fundamental symmetries
of QCD.
