NEW TOPOLOGIES IN THE PHASE DIAGRAM OF THE SEMI-INFINITE BLUME-CAPEL MODEL
Carla Buzano, Alessandro Pelizzola
The phase diagram of the Blume--Capel model on a semi--infinite simple cubic lattice with a (100) free surface is studied in the pair approximation of the cluster variation method.…
CVM ANALYSIS OF CROSSOVER IN THE SEMI-INFINITE ISING MODEL
Alessandro Pelizzola
The crossover behavior of the semi--infinite three dimensional Ising model is investigated by means of Padé approximant analysis of cluster variation method results. We give estima…
Cluster Variation Method, Pade` Approximants and Critical Behaviour
A. Pelizzola
In the present paper we show how non--classical, quite accurate, critical exponents can be extracted in a very simple way from the Padé analysis of the results obtained by mean fie…
The half-filled Hubbard model in the pair approximation of the Cluster Variation Method
Alessandro Pelizzola
The half filled Hubbard model is studied in the pair approximation of the Cluster Variation Method. The use of the symmetry of the model makes possible to give a complete a…
Surface reentrance in the semi-infinite spin-1 Ising models
Carla Buzano, Alessandro Pelizzola
The critical behavior of the semi-infinite Blume-Capel and Blume-Emery-Griffiths models is investigated in the pair approximation of the Cluster Variation Method. Equations for bul…
Multicritical Points And Reentrant Phenomenon In The BEG Model
Carla Buzano, Alessandro Pelizzola
The Blume - Emery - Griffiths model is investigated by use of the cluster variation method in the pair approximation. We determine the regions of the phase space where reentrant ph…
