HIGH-TEMPERATURE SERIES FOR THE RP(N-1) LATTICE SPIN MODEL (GENERALIZED MAIER-SAUPE MODEL OF NEMATIC LIQUID-CRYSTALS) IN 2 SPACE DIMENSIONS AND WITH GENERAL SPIN DIMENSIONALITY-N

[摘要] High-temperature series expansions of the spin-spin correlation functions of the RP(n-1) spin model on the square lattice are computed through order beta8 for general spin dimensionality n. Tables are reported for the expansion coefficients of the energy per site, the susceptibility, and the second correlation moment.
