Folding transitions of the square--diagonal two--dimensional lattice
E. N. M. Cirillo, G. Gonnella, A. Pelizzola
The phase diagram of a vertex model introduced by P. Di Francesco (Nucl. Phys. B 525, 507 1998) representing the configurations of a square lattice which can fold with different be…
On the low-temperature phase of the three-state antiferromagnetic Potts model on the simple cubic lattice
Alessandro Pelizzola
The three-state antiferromagnetic Potts model on the simple cubic lattice is investigated using the cluster variation method in the cube and the star-cube approximations. The broke…
Folding transition of the triangular lattice in a discrete three--dimensional space
Emilio N. M. Cirillo, Giuseppe Gonnella, Alessandro Pelizzola
A vertex model introduced by M. Bowick, P. Di Francesco, O. Golinelli, and E. Guitter (cond-mat/9502063) describing the folding of the triangular lattice onto the face centered cub…
Folding transitions of the triangular lattice with defects
Emilio N. M. Cirillo, Giuseppe Gonnella, Alessandro Pelizzola
A recently introduced model describing the folding of the triangular lattice is generalized allowing for defects in the lattice and written as an Ising model with nearest-neighbor…
Mean Field Renormalization Group for the Boundary Magnetization of Strip Clusters
A. Pelizzola, A. Stella
We analyze in some detail a recently proposed transfer matrix mean field approximation which yields the exact critical point for several two dimensional nearest neighbor Ising mode…
Low-Temperature Expansion for a First Order Surface Transition
C. Buzano, A. Pelizzola
The question concerning the possibility of a first order surface transition in a semi--infinite Blume--Capel model is addressed by means of low temperature expansions. It is found…
Cluster Variation Approach to the Random-Anisotropy Blume-Emery-Griffiths Model
C. Buzano, A. Maritan, A. Pelizzola
The random--anisotropy Blume--Emery--Griffiths model, which has been proposed to describe the critical behavior of He--He mixtures in a porous medium, is studied in the pai…
