Critical exponents of two-dimensional Potts and bond percolation models

Abstract

Critical exponents of the two-dimensional, q-state Potts model are calculated by means of finite size scaling and transfer matrix techniques for continuous q. Results for the temperature exponent agree accurately with the conjecture of den Nijs (1979). The magnetic exponent is found to behave in accordance with the conjecture of Nienhuis et al. (1980).
