The investigated hamiltonian has a form of the extended Hubbard model in the atomic limit (i.e., the zero-bandwidth limit) and the variational approach is used, which treats the onsite interaction term exactly and the intersite interactions within the mean-field approximation.

The investigation of the general case taking into account for the first time the effects of longer-ranged density-density interaction as well as possible phase separations shows that the Hubbard model can exhibit not only several homogeneous charge ordered (CO) phases, but also various phase separated states (CO-CO and CO-nonordered).

This study evidences that a finite-range order persists for a wide range of the temperature, as shown by the behavior of the correlation functions and by the two-peak structure exhibited by the charge susceptibility and the entropy.

This work studies the zero-bandwidth limit of the extended Hubbard model, which can be considered as a simple effective model of charge ordered insulators and derives the exact ground state diagrams for different lattice dimensionalities.
