A lattice of confining solitons to describe high-density nuclear matter
We examine the properties of an infinite system of solitons in the Wigner-Seitz approximation. The elementary building block of the studied soliton lattice is a nontopological confining soliton with a nonlocal coupling. We follow earlier work with other types of solitons and develop a crystal approximation for nuclear matter. This requires the self-consistent solution of the Dirac equation for quarks together with a nonlinear Klein-Gordon equation for the meson field generated in the model with boundary conditions appropriate to a Wigner-Seitz cell. When the size of the Wigner-Seitz cell becomes sufficiently small, quark energy bands develop, each soliton contributing one level to each band. Further increase in the density leads to band crossing, in analyogy with the insulator-conductor transition for metals. The intersection between the lowest occupied band with the next empty band signals a change in the properties of the soliton lattice. The nature of this transition will be discussed.
