Spin compensation temperatures in the mean-field approximation of a mixed spin-2 and spin-5/2 Ising ferrimagnetic system

Mohamad, Hadey K.; Domashevskaya, E.P.; Klinskikh, A.F. - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 22, pp. 4713-4718

The magnetic behaviors of a mixed spin-2 and spin-5/2 Ising ferrimagnetic system on a square lattice are studied with the mean-field approximation (MFA) based on the Bogoliubov inequality for the free energy. A Landau expansion of the free energy in the order parameter is also described in this...

EIGENMODE OF THE DECISION-BY-MAJORITY PROCESS IN COMPLEX NETWORKS

UCHIDA, MAKOTO; SHIRAYAMA, SUSUMU - In: Advances in Complex Systems (ACS) 11 (2008) 04, pp. 565-579

The nature of the dynamics of opinion formation or zero-temperature Ising models modeled as a decision-by-majority process in complex networks is investigated using eigenmode analysis. The Hamiltonian of the system is defined and estimated by eigenvectors of the adjacency matrix constructed from...
