Gaussian approximation for Ising model. Variational approach
A variant of a Gaussian approximation in Ising model of phase transition is suggested. The method of functional integration with the application of a variational method is put in the basis of the approach. The Hamiltonian (the functional) is presented which in the method of functional integration...
