New Algorithm of the Finite Lattice Method for the High-temperature Expansion of the Ising Model in Three Dimensions

الأصل · EN

We propose a new algorithm of the finite lattice method to generate the high-temperature series for the Ising model in three dimensions. It enables us to extend the series for the free energy of the simple cubic lattice from the previous series of 26th order to 46th order in the inverse temperature. The obtained series give the estimate of the critical exponent for the specific heat in high precision.
