A renormalization group study of the three-color Ashkin-Teller model on a Wheatstone hierarchical lattice
R. Teodoro, C. G. Bezerra, A. M. Mariz +1
We have investigated the three-color Ashkin-Teller model (3AT), on the Wheatstone bridge hierarchical lattice, by means of a Migdal-Kadanoff renormalization group approach. We have…

Tricriticality and Reentrance in a Naive Spin-Glass Model
F. A. da Costa
In this paper a spin-1 spin-glass model under the presence of a uniform crystal field is investigated. It is shown that the model presents both continuous and first-order phase tra…
