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…
Critical behavior of ferromagnetic spin models with aperiodic exchange interactions
T. A. S. Haddad, S. T. R. Pinho, S. R. Salinas
We review recent investigations of the critical behavior of ferromagnetic -state Potts models on a class of hierarchical lattices, with exchange interactions according to some d…
Field behavior of an Ising model with aperiodic interactions
Angsula Ghosh, T. A. S. Haddad, S. R. Salinas
We derive exact renormalization-group recursion relations for an Ising model, in the presence of external fields, with ferromagnetic nearest-neighbor interactions on Migdal-Kadanof…
Tricritical behaviour in deterministic aperiodic Ising systems
T. A. S. Haddad, Angsula Ghosh, S. R. Salinas
We use a mixed-spin model, with aperiodic ferromagnetic exchange interactions and crystalline fields, to investigate the effects of deterministic geometric fluctuations on first-or…
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…
Critical behavior of an Ising model with aperiodic interactions
S. T. R. Pinho, T. A. S. Haddad, S. R. Salinas
We write exact renormalization-group recursion relations for a ferromagnetic Ising model on the diamond hierarchical lattice with an aperiodic distribution of exchange interactions…
