2-Dimensional Ising Models  

In General > s.a. ising models; spin models; lattice field theory [random].
* Motivation: The 2D Ising model is the only non-trivial exactly solvable model of phase transition; 2016, Proof that all classical spin models are equivalent to 2D Ising models, with possibly position-dependent couplings and external fields.
* Summary: Without a magnetic field, one gets the Onsager solution (1940s) with a phase transition, while with a magnetic field exact results were obtained in the 1980s by Zamolodchikov, at the critical temperature.
