Correlation function of the two-dimensional Ising model on a finite lattice. II

A theoretical study ofa mixed spin Ising system consisting ofspin-1=2 and spin-1 with a random !eld is studied by the use ofthe !nite cluster approximation within the framework

We wish to gain insight into the interface in the Ising model with the help of our previous results and the classical coupling of Edwards and Sokal (see chapter 1 of [9] for

When H(t) is not of a simple sign in the time interval of interest, correlations between magnetic field values at different times come in..

Even though we should ixpect (for very large sizes) both exponents q and q~ to be such that dq < de it could be that for the sizes one is able to study with numerical techniques,

The partition function, pair correlation function and the zero-field susceptibility for the one-dimen- sional Ising model with arbitrary spin are shown to be expressed in

But we believe that in these shorter series the influence of other singularities was still very strong, so that the evaluation of the amplitude of the confluent

A comparison of our predictions for the spin-wave energy and damping with the experimental values deduced for CoF2 by neutron scattering [6] is limited by

modulated structures observed in other systems (V-Ni-Si, Mo-Cr-Fe). According to the electron diffraction patterns, these modulated phases are precursor states of the cubic
