Description	We investigate the properties of cold dense quark matter composed of two colors and two flavors of light quarks. In particular, we perform the first model calculation of the full phase diagram at nonzero baryon and isospin density, thus matching the model-independent predictions of chiral perturbation theory at low density to the conjectured phase structure at high density. We confirm the presence of the Fulde-Ferrell phase in the phase diagram and study its dependence on the tunable parameter in the Lagrangian that simulates the effects of the quantum axial anomaly. As a by-product, we clarify the calculation of the thermodynamic potential in the presence of the Fulde-Ferrell pairing, which was previously based on an ad hoc subtraction of an unphysical cutoff artifact.
