TL;DR
This paper investigates the crossover behavior in the semi-infinite 3D Ising model using Padé approximants of CVM results, providing estimates for critical exponents that align well with Monte Carlo simulations.
Contribution
It introduces a novel application of Padé approximants to CVM results for analyzing crossover phenomena in the semi-infinite 3D Ising model.
Findings
Critical and multicritical exponents estimated with high accuracy.
Results agree well with extensive Monte Carlo simulations.
Provides a new methodological approach for studying crossover behavior.
Abstract
The crossover behavior of the semi--infinite three dimensional Ising model is investigated by means of Pad\'e approximant analysis of cluster variation method results. We give estimates for ordinary critical as well as for multicritical exponents, which are in very good agreement with extensive Monte Carlo simulations.
