Energy density correlations in the three-dimensional Ising model
The energy-density-energy-density correlation function is studied in the three-dimensional Ising model in zero external field, for various spins on the fcc lattice. An extension of the linked-cluster technique is used to obtain high-temperature series expansions for the correlation function and its …

High-temperature critical indices for the classical anisotropic Heisenberg model
… A diagrammatic expansion for the Slpin-spin correlation function is derived and renormalized. The resulting form of the perturbation theory has been used to derive high-temperature series, for various lattices and anisotropies, through orderT (closepacked lattices) and T- 9 (loose-packed …
