Lars Onsager solved the Â square two dimensional form of it.
Griffith, Kelly, and Sherman collectively name inequalities for correlations in this model. One relation that arises from low temperature expansions of its is the KramersÂ–Wannier duality. Glauber dynamics can be used to study the cutoffs between its regimes, and mean field theory is commonly used to approximate this model. Â The minimum flipping energy is 4J in this theory, which is generalized by the (*) Potts model. It can be described through an equation in which the total energy is equated to an expression including a term of the Â negative exchange energy times sum over nearest neighbors in the lattice of a product of spins. Lars Onsager solved the Â square two dimensional form of it. For 10 points, name this simple statistical model of ferromagnetism.
