Ising model

Proper noun

Meaning

the Ising model

A particular mathematical model of ferromagnetism in statistical mechanics.

Examples

For example, mean field theory predicts a finite discontinuity of the heat capacity at the transition temperature, and the two-dimensional Ising model has a logarithmic divergence. Source: Internet

Later, there developed the idea that a finite number of generating operators could represent all the correlation functions of the Ising model. Source: Internet

The Ising model was solved exactly to show that spontaneous magnetization cannot occur in one dimension but is possible in higher-dimensional lattices. Source: Internet
