摘要
We performed Monte Carlo simulations of two-dimensional q-state Potts models with q = 10, 15, and 20 and measured the spin-spin correlation function at the first-order transition point beta(t) in the disordered and ordered phase. Our results for the correlation length xi(d)(beta(t)) in the disordered phase are compatible with an analytic formula. Estimates of the correlation length xi(o)(beta(t)) in the ordered phase yield strong numerical evidence that R drop xi(o)(beta(t))/xi(d)(beta(t)) = 1.
