Projected single-spin flip dynamics in the Ising Model
A. L. C. Ferreira, Raul Toral
We study transition matrices for projected dynamics in the energy-magnetization space, magnetization space and energy space. Several single spin flip dynamics are considered such a…
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…
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…
Optimized multicanonical simulations: a new proposal based on classical fluctuation theory
J. Viana Lopes, Miguel D. Costa, J. M. B. Lopes dos Santos +1
We propose a new recursive procedure to estimate the microcanonical density of states in multicanonical Monte Carlo simulations which relies only on measurements of moments of the…
Coherent regimes of mutually coupled Chua's circuits
I. Gomes Da Silva, S. De Monte, F. d'Ovidio +2
We study the dynamical regimes that emerge from the strongly coupling between two Chua's circuits with parameters mismatch. For the region around the perfect synchronous state we s…
Distribution of winners in truel games
R. Toral, P. Amengual
In this work we present a detailed analysis using the Markov chain theory of some versions of the truel game in which three players try to eliminate each other in a series of one-t…
