摘要：

Using Finite-Size Scaling techniques, we numerically show that the first irrelevant operator of the lattice lambda phi(4) theory in three dimensions is (within errors) completely decoupled at lambda = 1.0. This interesting result also holds in the Thermodynamical Limit, where the renormalized coupling constant shows an extraordinary reduction of the scaling-corrections when compared with the Ising model. It is argued that Finite-Size Scaling analysis can be a competitive method for finding improved actions. (C) 1998 Elsevier Science B.V. All rights reserved.
