CRITICAL EXPONENTS OF THE 3-DIMENSIONAL CLASSICAL PLANE-ROTATOR MODEL ON THE SC LATTICE FROM A HIGH-TEMPERATURE-SERIES ANALYSIS
[摘要] High-temperature-series expansions of the spin-spin correlation function for the plane rotator (or XY) model on the sc lattice are extended by three terms through order beta17. Tables of the expansion coefficients are reported for the correlation function spherical moments of order l = 0, 1, 2. Our analysis of the series leads to fairly accurate estimates of the critical parameters.
