On the low temperature series expansion for the diagonal correlation functions in the two-dimensional Ising model

arXiv:cond-mat/0505166

Abstract

A previously tested differential equation method for generating low temperature series expansion for diagonal spin-spin correlation functions in the d=2 Ising model is extended to generate the non-universal terms for arbitrary separation of the spins. This extends the earlier calculations of these correlation functions.
