Description
I will review our current understanding of the phase diagram of two-color quark matter with emphasis on the comparison of model and lattice results. Reproducing even *qualitatively* the thermodynamic observables measured on the lattice requires augmenting the standard Polyakov loop Nambu-Jona-Lasinio model with two new elements: renormalization of the Polyakov loop, and explicit chiral symmetry breaking in the contact interaction. Finally, I will argue how the lattice data for the Polyakov loop expectation value in cold and dense two-color matter may be used to improve existing models of the real, three-color world.
