Critical temperature difference between Ising and XY model
e−2K = 1 2 + 2 − n− −−−−√− −−−−−−−−√ e − 2 K = 1 2 + 2 − n. with K = βJ K = β J. Numerically, it says that: Ising model (n = 1) has K ≈ 0.27 K ≈ 0.27. XY model (n=2) has K ≈ 0.17 K ≈ 0.17. Thus, the critical temperature for the XY model is higher than the Ising model.Explore further
