Finite size effects on measures of critical exponents in d=3 O(N) models

Abstract

We study the critical properties of three-dimensional O(N) models, for N=2,3,4. Parameterizing the leading corrections-to-scaling for the exponent, we obtain a reliable infinite volume extrapolation, incompatible with previous Monte Carlo values, but in agreement with -expansions. We also measure the critical exponent related with the tensorial magnetization as well as the exponents and critical couplings.
