Topology Induced Coarsening in Language Games
A. Baronchelli, L. Dall'Asta, A. Barrat +1
We investigate how very large populations are able to reach a global consensus, out of local "microscopic" interaction rules, in the framework of a recently introduced class of mod…
Energy fluctuations in vibrated and driven granular gases
P. Visco, A. Puglisi, A. Barrat +2
We investigate the behavior of energy fluctuations in several models of granular gases maintained in a non-equilibrium steady state. In the case of a gas heated from a boundary, th…
Strategies for fast convergence in semiotic dynamics
Andrea Baronchelli, Luca Dall'Asta, Alain Barrat +1
Semiotic dynamics is a novel field that studies how semiotic conventions spread and stabilize in a population of agents. This is a central issue both for theoretical and technologi…
K-core decomposition of Internet graphs: hierarchies, self-similarity and measurement biases
José Ignacio Alvarez-Hamelin, Luca Dall'Asta, Alain Barrat +1
We consider the -core decomposition of network models and Internet graphs at the autonomous system (AS) level. The -core analysis allows to characterize networks beyond the d…
Fluctuations of power injection in randomly driven granular gases
P. Visco, A. Puglisi, A. Barrat +2
We investigate the large deviation function pi(w) for the fluctuations of the power W(t)=w t, integrated over a time t, injected by a homogeneous random driving into a granular gas…
Fluctuations of internal energy flow in a vibrated granular gas
A. Puglisi, P. Visco, A. Barrat +2
The non-equilibrium fluctuations of power flux in a fluidized granular media have been recently measured in an experiment [Phys. Rev. Lett. 92, 164301, 2004], which was announced t…
