Imperfect bifurcations in opinion dynamics under external fields
Francisco Freitas, Allan R. Vieira, Celia Anteneodo
We investigate, through a kinetic-exchange model, the impact that an external field, like advertising and propaganda, has on opinion dynamics. We address the situations where two o…
Dynamical robustness of discrete conservative systems: Harper and generalized standard maps
Ugur Tirnakli, Constantino Tsallis, Kivanc Cetin
In recent years, statistical characterization of the discrete conservative dynamical systems (more precisely, paradigmatic examples of area-preserving maps such as the standard and…
Memory and irreversibility on two-dimensional overdamped Brownian dynamics
Eduardo dos S. Nascimento, Welles A. M. Morgado
We consider the effects of memory on the stationary behavior of a two-dimensional Langevin dynamics in a confining potential. The system is treated in an overdamped approximation a…
Wealth Distribution Models with Regulations: Dynamics and Equilibria
Ben-Hur Francisco Cardoso, Sebastián Gonçalves, José Roberto Iglesias
Simple agent based exchange models are a commonplace in the study of wealth distribution in an artificial economy. Generally, in a system that is composed of many agents characteri…
Order-disorder transition in a two-dimensional associating lattice gas
A. P. Furlan, Tiago J. Oliveira, Jürgen F. Stilck +1
We study an associating lattice gas (ALG) using Monte Carlo simulation and solutions on Husimi lattices. In this model, the molecules have an orientational degree of freedom and th…
Hamiltonian dynamics of the SIS epidemic model with stochastic fluctuations
Gilberto M. Nakamura, Alexandre S. Martinez
Empirical records of epidemics reveal that fluctuations are important factors for the spread and prevalence of infectious diseases. The exact manner in which fluctuations affect sp…
