Critical exponents for the long-range Ising chain using a transfer matrix approach
Roberto F. S. Andrade, Suani T. R. Pinho
The critical behavior of the Ising chain with long-range ferromagnetic interactions decaying with distance , , is investigated using a numerically efficient transfer ma…

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…
