Further extensions of the high-temperature expansions for the two-dimensional classical XY model on the triangular and the square lattices
P. Butera, M. Pernici
The high-temperature expansions for the spin-spin correlation function of the two-dimensional classical XY (planar rotator) model are extended by two terms, from order 24 through o…
High-precision determination of universal amplitude ratios for the q=3 Potts model in 2d
Lev N. Shchur, Bertrand Berche, Paolo Butera
Monte Carlo simulations and series expansion data for the energy, specific heat, magnetization and susceptibility of the 3-state Potts model on the square lattice are analyzed in t…
High-temperature expansions through order 24 for the two-dimensional classical XY model on the square lattice
P. Butera, M. Pernici
The high-temperature expansion of the spin-spin correlation function of the two-dimensional classical XY (planar rotator) model on the square lattice is extended by three terms, fr…
A study of logarithmic corrections and universal amplitude ratios in the two-dimensional 4-state Potts model
Lev Shchur, Bertrand Berche, Paolo Butera
Monte Carlo (MC) and series expansion (SE) data for the energy, specific heat, magnetization and susceptibility of the two-dimensional 4-state Potts model in the vicinity of the cr…
Enumeration of the self-avoiding polygons on a lattice by the Schwinger-Dyson equations
P. Butera, M. Comi
We show how to compute the generating function of the self-avoiding polygons on a lattice by using the statistical mechanics Schwinger-Dyson equations for the correlation functions…
