Lattice statistical models for the nematic transitions in liquid-crystalline systems
E. S. Nascimento, A. P. Vieira, S. R. Salinas
We investigate the connections between some simple Maier-Saupe lattice models, with a discrete choice of orientations of the microscopic directors, and a recent proposal of a two-t…
Chaotic behavior of a spin-glass model on a Cayley tree
F. A. da Costa, J. M. de Araujo, S. R. Salinas
We investigate the phase diagram of a spin--1 Ising spin-glass model on a Cayley tree. According to early work of Thompson and collaborators, this problem can be formulated in term…
Critical behavior of spin and polymer models with aperiodic interactions
T. A. S. Haddad, S. R. Salinas
We review and extend some recent investigations of the effects of aperiodic interactions on the critical behavior of ferromagnetic -state Potts models. By considering suitable d…
Universal Critical Behavior of Aperiodic Ferromagnetic Models
T. A. S. Haddad, S. T. R. Pinho, S. R. Salinas
We investigate the effects of geometric fluctuations, associated with aperiodic exchange interactions, on the critical behavior of -state ferromagnetic Potts models on generaliz…
Critical behavior of the Ising model on a hierarchical lattice with aperiodic interactions
S. T. R. Pinho, T. A. S. Haddad, S. R. Salinas
We write exact renormalization-group recursion relations for nearest-neighbor ferromagnetic Ising models on Migdal-Kadanoff hierarchical lattices with a distribution of aperiodic e…
