Фазовый переход порядок-беспорядок на языке конфигурационной энтропии

Фазовый переход порядок-беспорядок на языке конфигурационной энтропии

Abstract

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 ф4) 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 ф6). Particular attention is given to the justification of applicability of the relationship between non-equilibrium order parameter and configuration entropy.

Теория фазового перехода порядок-беспорядок формулируется на эквивалентном языке конфигурационной энтропии. Такая формулировка позволяет выделить тонкие особенности формализма, связанные с существованием равновесных состояний. На основании сопоставления описания на языке энтропии и на языке параметра порядка (модель ф4) рассматривается модель, в которой неупорядоченная (аморфная или стекольная) фаза может существовать и ниже температуры Кюри в метастабильном состоянии. Кроме того, предлагается новая модель (полностью в духе теории Ландау), в которой также возможно существование метастабильного аморфного состояния (модель ф6). Особое внимание уделено обоснованию применимости формулы связи между неравновесным параметром порядка и конфигурационной энтропией.
