Species survival and scaling laws in hostile and disordered environments
Rodrigo P. Rocha, Wagner Figueiredo, Samir Suweis +1
In this work we study the likelihood of survival of single-species in the context of hostile and disordered environments. Population dynamics in this environment, as modeled by the…
Prisoner's dilemma on directed networks
A. L. Ferreira, A. Lipowski, T. B. Pedro +2
We study the prisoner's dilemma model with a noisy imitation evolutionary dynamics on directed out-homogeneous and uncorrelated directed random networks. An heterogeneous pair mean…
Novel considerations about the non-equilibrium regime of the tricritical point in a metamagnetic model: localization and tricritical exponents
Roberto da Silva, Henrique Almeida Fernandes, José Roberto Drugowich de Felício +1
We have investigated the time-dependent regime of a two-dimensional metamagnetic model at its tricritical point via Monte Carlo simulations. First of all, we obtained the temperatu…
Criticality and Chaos in Systems of Communities
Massimo Ostilli, Wagner Figueiredo
We consider a simple model of communities interacting via bilinear terms. After analyzing the thermal equilibrium case, which can be described by an Hamiltonian, we introduce the d…
Emergence of chaos in interacting communities
M. Ostilli, W. Figueiredo
We introduce a simple dynamical model of two interacting communities whose elements are subject to stochastic discrete-time updates governed by only bilinear interactions. When the…
Ion Specificity and Micellization of Ionic Surfactants: A Monte Carlo Study
Alexandre P. dos Santos, Wagner Figueiredo, Yan Levin
We develop a simulation method which allows us to calculate the critical micelle concentrations for ionic surfactants in the presence of different salts. The results are in good ag…
