Calculation of the shift exponent for the two-layer three-state Potts model using the transfer matrix method.
A finite-size scaling approach based on the transfer matrix method is developed to calculate the critical temperature and critical exponent of the symmetric and the asymmetric two-layer three-state Potts models. For similar intralayer interactions our calculation of the shift exponent phi confirm some scaling arguments which predict phi = gamma, where gamma is the susceptibility exponent. For unequal intralayer interactions we have obtained phi = 0.5 which differ from the prediction phi = gamma/2 of a generalized mean-field theory.
