Abstract
We apply and test the recently proposed “extended scaling” scheme in an analysis
of the magnetic susceptibility of Ising systems above the upper critical dimension.
The data are obtained by Monte Carlo simulations using both the conventional Wolff
cluster algorithm and the Prokof ’ev-Svistunov worm algorithm. As already observed
for other models, extended scaling is shown to extend the high-temperature critical
scaling regime over a range of temperatures much wider than that achieved conventionally.
It allows for an accurate determination of leading and sub-leading scaling
indices, critical temperatures and amplitudes of the confluent corrections.
