Large-q expansion of the specific heat for the two-dimensional q-state Potts model
Abstract
We have calculated the large-q expansion for the specific heat at the phase transition point in the two-dimensional q-state Potts model to the 23rd order in 1/q using the finite lattice method. The obtained series allows us to give highly convergent estimates of the specific heat for q>4 on the first order transition point. The result confirm us the correctness of the conjecture by Bhattacharya et al. on the asymptotic behavior of the specific heat for q 4+.
