The Blume-Emery-Griffiths model at the FAD and AD interfaces
Paulo C. Lima, Riccardo Mariani, Aldo Procacci +1
We analyse the Blume-Emery-Griffiths (BEG) model on the lattice $\Zd$ at the ferromagnetic-antiquadrupolar-disordered (FAD) and antiquadrupolar-disordered (AD) interfaces of parame…

Uniqueness of the Gibbs state of the BEG model in the disordered region of parameters
Paulo C Lima
We show that the -dimen\-sion\-al Blume-Emery-Griffiths model has a unique Gibbs state, for all temperature, in some portion of disordered region of parameters, ruling out the p…

Absolute convergence of the free energy of the BEG model in the disordered region for all temperatures
Paulo C. Lima, Ricardo Lopes de Jesus, Aldo Procacci
We analyze the d-dimensional Blume-Emery-Griffiths model in the disordered region of parameters and we show that its free energy can be explicitly written in term of a series which…
