Effective potentials of quarks in non-Abelian chromomagnetic fields

Thermodynamic potential quark-antiquark gas in a stationary chromomagnetic field in one-loop approximation is calculated, taking into account non-zero chemical potential. It is shown that the thermodynamic potential is a smooth function of temperature, field and chemical potential is considered range of their variation. The conclusion is made on the absence of quark-antiquark plasma-hadrons phase transition in the given model
