High-temperature expansion of the magnetic susceptibility and higher moments of the correlation function for the two-dimensional XY model

H. Arisue

We calculate the high-temperature series of the magnetic susceptibility and the second and fourth moments of the correlation function for the XY model on the square lattice to orde…

High-Temperature Expansion of the Free Energy in the Two-Dimensional XY Model

Hiroaki Arisue

We extend the high-temperature series of the free energy for the XY model in two dimensions to order from the previous order of by applying the improved algorithm…
