High resolution dynamical mapping of social interactions with active RFID
Alain Barrat, Ciro Cattuto, Vittoria Colizza +3
In this paper we present an experimental framework to gather data on face-to-face social interactions between individuals, with a high spatial and temporal resolution. We use activ…
Microdynamics in stationary complex networks
Aurelien Gautreau, Alain Barrat, Marc Barthelemy
Many complex systems, including networks, are not static but can display strong fluctuations at various time scales. Characterizing the dynamics in complex networks is thus of the…
Renormalization flows in complex networks
Filippo Radicchi, Alain Barrat, Santo Fortunato +1
Complex networks have acquired a great popularity in recent years, since the graph representation of many natural, social and technological systems is often very helpful to charact…
Fluctuations in granular gases
A. Barrat, A. Puglisi, E. Trizac +2
A driven granular material, e.g. a vibrated box full of sand, is a stationary system which may be very far from equilibrium. The standard equilibrium statistical mechanics is there…
Complex networks renormalization: flows and fixed points
Filippo Radicchi, José Javier Ramasco, Alain Barrat +1
Recently, it has been claimed that some complex networks are self-similar under a convenient renormalization procedure. We present a general method to study renormalization flows i…
Consensus formation on coevolving networks: groups' formation and structure
Balazs Kozma, Alain Barrat
We study the effect of adaptivity on a social model of opinion dynamics and consensus formation. We analyze how the adaptivity of the network of contacts between agents to the unde…
