We discuss an extension of the dyon-anti-dyon liquid model that includeslight quarks in the dense center symmetric Coulomb phase. In this work, like inour previous one, we use the simplest color SU(2) group. We start with a singlefermion flavor $N_f=1$ and explicitly map the theory onto a 3-dimensionalquantum effective theory with a fermion that is only U$_V(1)$ symmetric. We useit to show that the dense center symmetric plasma develops, in the mean fieldapproximation, a nonzero chiral condensate, although the ensuing Goldstone modeis massive due to the U$_A(1)$ axial-anomaly. We estimate the chiral condensateand $\sigma,\eta$ meson masses for $N_f=1$. We then extend our analysis toseveral flavors $N_f>1$ and colors $N_c>2$ and show that center symmetry andspontaneous chiral symmetry breaking disappear simultaneously when$x=N_f/N_c\geq 2$ in the dense plasma phase. A reorganization of the denseplasma phase into a gas of dyon-antidyon molecules restores chiral symmetry,but may preserve center symmetry in the linearized approximation. We estimatethe corresponding critical temperature.
