Blume-Emery-Griffiths model on Random Graphs
R. Erichsen, Alexandre Silveira, S. G. Magalhaes
The Blume-Emery-Griffiths model with a random crystal field is studied in a random graph architecture, in which the average connectivity is a controllable parameter. The disordered…
Geometrical Frustration and Cluster Spin Glass with Random Graphs
Alexandre Silveira, R. Erichsen, S. G. Magalhaes
We develop a novel method based in the sparse random graph to account the interplay between geometric frustration and disorder in cluster magnetism. Our theory allows to introduce…
Ising spin glass in a random network with a gaussian random field
R. Erichsen, A. Silveira, S. G. Magalhaes
We investigate thermodynamic phase transitions of the joint presence of spin glass (SG) and random field (RF) using a random graph model that allows us to deal with the quenched di…
