Abstract
Three-dimensional spin models of the Ising and XY universality classes are studied by a combination of high temperature expansions and Monte Carlo sim ulations. Critical exponents are determined to very high precision. Scaling amplitude ratios are computed via the critical equation of state. Our resu lts are compared with other theoretical computations and with experiments: with special emphasis on the lambda transition of He-4.
