  An infinite system of nonlocal, individually confining solitons is considered
as a model of high-density nuclear matter. The soliton-lattice problem is
discussed in the Wigner-Seitz approximation. The cell size is varied to study
the density dependence of physical quantities of interest. A transition to a
system where quarks can migrate between solitons is found. We argue that this
signals quark deconfinement. The model is applied to the calculation of
selected in-medium properties.
