Diluted Ising model with competing interactions

Andrade, R.F.S; Salinas, S.R - In: Physica A: Statistical Mechanics and its Applications 270 (1999) 3, pp. 342-352

We introduce aperiodic, but deterministic, dilution of bonds in the Ising model with competing ferro and antiferromagnetic interactions between first and second neighbors along the branches of a Cayley tree. The problem is formulated as a non-linear dissipative map, whose attractors correspond...

Evolutionary model of stock markets

Kaldasch, Joachim - In: Physica A: Statistical Mechanics and its Applications 415 (2014) C, pp. 449-462

replicator equation. This allows quantifying the evolutionary price competition between stocks. The theory suggests that stock … competition that follows from the model is illustrated by examining the empirical long-term price trends of two stocks. …

The paradox of group behaviors based on Parrondo’s games

Xie, Neng-gang; Guo, Jia-yi; Ye, Ye; Wang, Chao; Wang, Lu - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 23, pp. 6146-6155

. In game A, two behavioral patterns are defined: competition and inaction. A controlled alternation strategy of behavioral … competition behavior of game A that is essential for the total capital to grow. However, if game B is the history …-dependent version, this counter-intuitive phenomenon will not happen. The reason is selfish voting results in the competition behavior …

Minority mechanisms in models of agents learning collectively a resource level

Challet, Damien - In: Physica A: Statistical Mechanics and its Applications 344 (2004) 1, pp. 24-29

Starting from the Minority Game and building more and more sophisticated models of adaptive agents, we show that minority mechanisms underly any model where agents learn collectively a resource level that can be either obvious and constant in time, obvious and time-varying, or hidden.

A Blume–Capel spin glass with competing crystal-field interactions on a hierarchical lattice

Snowman, Daniel P. - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 9, pp. 1505-1515

Renormalization-group methods are used with a hierarchical lattice to model a Blume–Capel spin glass with annealed vacancies and competing crystal-field interactions. The strength of competing cross-link interactions is progressively increased as the effects, upon the phase diagrams, are...
