Scaling corrections: site percolation and Ising model in three dimensions

© 1999 IOP Publishing Ltd. We acknowledge interesting discussions with D Stauffer and R Ziff. We thank CICyT (AEN97-1708 and AEN97-1693) for partial financial support. The computations have been carried out using the RTNN machines at Universidad de Zaragoza and Universidad Complutense de Madrid.Using Finite-Size Scaling techniques we obtain accurate results for critical quantities of the Ising model and the site percolation, in three dimensions. We pay special attention in parameterizing the corrections-to-scaling, what is necessary to put the systematic errors below the statistical ones.Depto. de Física TeóricaFac. de Ciencias FísicasTRUECICyT, Spainpu
