The Ising system with an interaction of finite range on the Cayley tree

T. Morita

Physica A: Statistical Mechanics and its Applications, 1976, vol. 83, issue 2, 411-418

Abstract: It is shown that the thermodynamic properties and the distribution functions of the Ising systems on the Cayley tree are generally obtained in terms of the solution of a recurrence formula, when the interaction is of finite range. For the Bethe lattice where the boundary effects are ignored, the properties are given in terms of the solution of a nonlinear eigenvalue problem. It is further shown that a certain approximation in the cluster variation method is exact for this system and the equations determining the parameters occurring in this method are equivalent to the obtained nonlinear eigenvalue problem.
