    "abstract": "The quark exchange model is a simple realization of an adiabatic\napproximation to the strong-coupling limit of Quantum Chromodynamics (QCD): the\nquarks always coalesce into the lowest energy set of flux tubes. Nuclear matter\nis thus modeled in terms of its quarks. We wish to study the correlations\nimposed by total wavefunction antisymmetry when color degrees of freedom are\nincluded. To begin with, we have considered one-dimensional matter with a\n$SU(2)$ color internal degree of freedom only. We proceed by constructing a\ntotally antisymmetric, color singlet {\\it Ansatz} characterized by a\nvariational parameter $\\lambda$ (which describes the length scale over which\ntwo quarks in the system are clustered into hadrons) and by performing a\nvariational Monte Carlo calculation of the energy to optimize $\\lambda$ for a\nfixed density. We calculate the $q-q$ correlation function as well, and discuss\nthe qualitative differences between the system at low and high density.",
