Abstract:
A generalization of the molecular field method is considered on the example of
the Ising model. The main idea of the method proposed consists in that the real field
of the medium in arbitrary dynamic system is modelled by a certain random field, the
distribution function of which is determined from variational principle. It is assumed
that the entropy of the random field defined as the information entropy, plays an essential
part in achieving the self-consistence of the random field distribution function with
the dynamical system.
