New algorithm of the high-temperature expansion for the Ising model in three dimensions
Abstract
New algorithm of the finite lattice method is presented to generate the high-temperature expansion series of the Ising model. It enables us to obtain much longer series in three dimensions when compared not only to the previous algorithm of the finite lattice method but also to the standard graphical method. It is applied to extend the high-temperature series of the simple cubic Ising model from beta26 to beta46 for the free energy and from beta25 to beta32 for the magnetic susceptibility.
