Replica-symmetric solutions of a dilute Ising ferromagnet in a random field

M. O. Hase, J. R. L. de Almeida, S. R. Salinas

We use the replica method in order to obtain an expression for the variational free energy of an Ising ferromagnet on a Viana-Bray lattice in the presence of random external fields…

Intensity Coding in Two-Dimensional Excitable Neural Networks

Mauro Copelli, Osame Kinouchi

In the light of recent experimental findings that gap junctions are essential for low level intensity detection in the sensory periphery, the Greenberg-Hastings cellular automaton…

Complex dynamics in a one--block model for earthquakes

Raul Montagne, G. L. Vasconcelos

A two-dimensional earthquake model that consists of a single block resting upon a slowly moving rough surface and connected by two springs to rigid supports is studied. Depending o…

Chaos induced coherence in two independent food chains

Adriana Auyuanet, Arturo C. Marti, Raul Montagne

Coherence evolution of two food web models can be obtained under the stirring effect of chaotic advection. Each food web model sustains a three--level trophic system composed of in…

Majority-vote model on random graphs

Luiz F. C. Pereira, F. G. Brady Moreira

The majority-vote model with noise on random graphs has been studied. Monte Carlo simulations were performed to characterize the order-disorder phase transition appearing in the sy…
