Logarithmic corrections and universal amplitude ratios in the 4-state Potts model

Physics Procedia. 2010. Vol. 7. P. 7-18.
Berche B., Butera P., Shchur L.

Monte Carlo and series expansion data for the energy, specific heat, magnetisation and susceptibility of the 4-state Potts model in the vicinity of the critical point are analysed. The role of logarithmic corrections is discussed. Estimates of universal ratios A+/A−,Γ+/ΓL,ΓT/ΓL and  are given.
