Abstract

We consider the derived critical temperature (Tc) from the exact solution of the 2D square Ising model as a reference for approximation. Previous approximations accurately represent Tc as a function of the anisotropic parameter (α) only for low anisotropies. To accurately represent Tc at high anisotropies, we employed a limit approach with α approaching a large number. Additionally, we utilized the Lambert W function to express Tc as a function of α.
