We consider the p-spin model with spin 1/2 on all pure Husimi lattices. Using an effective
representation of the recursion relations, the phase transitions of the model on all pure …

We investigate the second order phase transitions of the ferromagnetic spin-1 Ising model
on pure Husimi lattices built up from elementary squares with arbitrary values of the …

We consider the Ising spin 1/2 model on arbitrary pure Husimi lattices. An effective
representation for the recursion relations is found which allows to write the general solution …

We investigate the second order phase transitions of the ferromagnetic spin-1 Ising model
on pure Husimi lattices built up from elementary triangles with arbitrary values of the …

A generalized mixed spin model with anisotropic interactions is considered on the union
jack lattice. We find that the model is equivalent to a free fermion model. The critical …

We investigate the multisite spin-1/2 Ising-like model in the presence of the external
magnetic field on the pure Husimi lattice with three sites in the elementary polygon (p= 3) …

We present estimates of the critical temperature of both higher-spin Ising and Potts models
on the square and simple cubic lattices based on a Husimi tree, dynamical systems …

Thermodynamic properties of the mixed spin-1 and spin-1/2 Ising–Heisenberg model are
studied on a honeycomb lattice using a new approach in the mean-field approximation to …

The ground state and zero-temperature magnetization process of the spin-1/2 Ising-
Heisenberg model on two-dimensional triangles-in-triangles lattices are exactly calculated …

We investigate the anti-ferromagnetic spin-1/2 1/2 Ising model with the presence of the
multisite interaction on the pure Husimi lattice with three sites in the elementary polygon (p …
