Exactly solvable $d$-dimensional model of a structural phase transition

N. M. Plakida, N. S. Tonchev


Abstract: The approximating Hamiltonian method is used to show that the lattice model $g\varphi^4$ with coupling constant $g=\lambda/N$ has an exact solution. The thermodynamics of the phase transition in this model is investigated.
