Deconfinement transition for nonzero baryon density in the field correlator method

Deconfinement phase transition due to the disappearance of confining colorelectric field correlators is described using a nonperturbative equation of state. The resulting transition temperature Tc(μ) at any chemical potential μ is expressed in terms of the change of the gluon condensate ΔG2 and absolute value of the Polyakov loop Lfund(Tc), which is known from the lattice and analytic data, and is in good agreement with the lattice data for ΔG2 ≈ 0.0035 GeV4; e.g., Tc(0) = 0.27, 0.19, and, 0.17 GeV for nf = 0, 2, and 3, respectively.
