P. Butera et al., CRITICAL EXPONENTS OF THE 3-DIMENSIONAL CLASSICAL PLANE-ROTATOR MODELON THE SC LATTICE FROM A HIGH-TEMPERATURE-SERIES ANALYSIS, Physical review. B, Condensed matter, 48(18), 1993, pp. 13987-13990
High-temperature-series expansions of the spin-spin correlation functi
on for the plane rotator (or XY) model on the sc lattice are extended
by three terms through order beta17. Tables of the expansion coefficie
nts are reported for the correlation function spherical moments of ord
er l = 0, 1, 2. Our analysis of the series leads to fairly accurate es
timates of the critical parameters.
