Order-desorder phase transition on the language of configuration entropy
The theory of phase transition order - disorder is formulated in the equivalent language of the configuration entropy. This formulation allows us to distinguish delicate features of the formalism associated with the existence of equilibrium states. Based on this parallel state as entropy language and the language of the order parameter (model ф<sub>4</sub>) a new model in which a disordered (amorphous or glass) phase may exist below the Curie temperature in a metastable state was proposed. In addition, the proposed new model is completely analogous to the theory of Landau, which can exist as a metastable amorphous state (model ф<sub>6</sub>). Particular attention is given to the justification of applicability of the relationship between non-equilibrium order parameter and configuration entropy.
