Phase diagram of the mixed spin-2 and spin-5/2 Ising system with two different single-ion anisotropies

da Cruz Filho, J.S.; Godoy, M.; de Arruda, A.S. - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 24, pp. 6247-6254

We study the effect of two different single-ion anisotropies in the phase diagram and in the compensation temperature of mixed spin-2 and spin-5/2 Ising ferrimagnetic system. We employed the mean-field theory based on the Bogoliubov inequality for Gibbs free energy. We use the Landau expansion...

Structure properties of evolutionary spatially embedded networks

Hui, Z.; Li, W.; Cai, X.; Greneche, J.M.; Wang, Q.A. - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 8, pp. 1909-1919

This work is a modeling of evolutionary networks embedded in one or two dimensional configuration space. The evolution is based on two attachments depending on degree and spatial distance. The probability for a new node n to connect with a previous node i at distance rni follows...

The ambivalent effect of lattice structure on a spatial game

Zhang, Hui; Gao, Meng; Li, Zizhen; Maa, Zhihui; Wang, … - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 11, pp. 1961-1972

life-history assumptions. Mean-field approximation fails to predict the outcome of computer simulations. Pair approximation … analyse the dynamics depending on major parameters. Mathematical analyses based on invasion probability analysis, mean-field … approximation, as well as pair approximation are also used. We find that the lattice structure promotes the evolution of cooperation …
