Molecular-field theory method for evaluating critical points of the Ising model.
The molecular-field theory is one of the most common approximations used to calculate properties of materials with the Ising model. A generalization, improving the previous results of molecular-field theory, is proposed. It has also been shown that this method distinguishes between two lattices with different geometries but equal numbers of nearest neighbors, such as square, diamond, triangular, and simple cubic lattices, a result that is missing from most other mean-field approaches.
