摘要：We study effective Polyakov loop models for SU(3) Yang-Mills theory at finite temperature. A
comprehensive mean field analysis of the phase diagram is carried out and compared to the results
obtained from Monte-Carlo simulations. We find a rich phase structure including ferromagnetic
and antiferromagnetic phases. Due to the presence of a tricritical point the mean field approximation
agrees very well with the numerical data. Critical exponents associated with second-order
transitions coincide with those of the Z3 Potts model. Finally, we employ inverse Monte-Carlo
methods to determine the effective couplings in order to match the effective models to Yang-Mills
theory.
