We study SU(2) lattice gauge theory with two flavors of Wilson fermion at non-zero chemical potential μ and low temperature on a 8 × 16 system. We identify three régimes along the μ-axis. For μ . mπ/2 the system remains in the vacuum phase, and all physical observables considered remain essentially unchanged. The intermediate régime is characterised by a non-zero diquark condensate and an assoc...
