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…
