Collective effects induced by diversity in extended systems
Raúl Toral, Claudio J. Tessone, João Viana Lopes
We show that diversity, in the form of quenched noise, can have a constructive effect in the dynamics of extended systems. We first consider a bistable model composed by many…
Finite size effects in the dynamics of opinion formation
Raul Toral, Claudio J. Tessone
For some models of relevance in the social sciences we review some examples in which system size plays an important role in the final outcome of the dynamics. We discuss the condit…
Stochastic Resonance in an Extended FitzHugh-Nagumo System: the Role of Selective Coupling
C. J. Tessone, H. S. Wio
Here we present a study of stochastic resonance in an extended FitzHugh-Nagumo system with a field dependent activator diffusion. We show that the system response (here measured th…
Diversity-induced resonance
Claudio J. Tessone, Claudio R. Mirasso, Raul Toral +1
We present conclusive evidence showing that different sources of diversity, such as those represented by quenched disorder or noise, can induce a resonant collective behavior in an…
