Description

Based on numerical simulation of two-color QCD in lattice regularization, correlations between fluctuations of the quark condensate, the net-quark number density, and the Polyakov loop are estimated.
For the pion mass $\sim 700$~MeV, there is a significant correlation at temperatures of $200-320$~MeV, which indicates a connection between the dynamics of chiral symmetry restoration and confinement at zero baryon number density.
It is also shown that, with an increase in the baryon chemical potential, this correlation disappears giving some evidence for the difference in the mechanisms of the chiral transition and the transition to deconfinement at $\mu_B > T_c$.
