Synchronised firing induced by network dynamics in excitable systems
Claudio J. Tessone, Damián H. Zanette
We study the collective dynamics of an ensemble of coupled identical FitzHugh--Nagumo elements in their excitable regime. We show that collective firing, where all the elements per…
Synchronization and structure in an adaptive oscillator network
Pablo M. Gleiser, Damián H. Zanette
We analyze the interplay of synchronization and structure evolution in an evolving network of phase oscillators. An initially random network is adaptively rewired according to the…
Coevolution of agents and networks: Opinion spreading and community disconnection
Santiago Gil, Damian H. Zanette
We study a stochastic model for the coevolution of a process of opinion formation in a population of agents and the network which underlies their interaction. Interaction links can…
Synchronization and frustration in oscillator networks with attractive and repulsive interactions
Damian H. Zanette
We study, numerically and analytically, the stability of synchronization for an ensemble of coupled phase oscillators with attractive and repulsive interactions, as a function of t…
Disturbing synchronization: Propagation of perturbations in networks of coupled oscillators
D. H. Zanette
We study the response of an ensemble of synchronized phase oscillators to an external harmonic perturbation applied to one of the oscillators. Our main goal is to relate the propag…
Propagation of small perturbations in synchronized oscillator networks
Damian H. Zanette
We study the propagation of a harmonic perturbation of small amplitude on a network of coupled identical phase oscillators prepared in a state of full synchronization. The perturba…
Dynamical systems with time-dependent coupling: Clustering and critical behaviour
Damian H. Zanette, Alexander S. Mikhailov
We study the collective behaviour of an ensemble of coupled motile elements whose interactions depend on time and are alternatively attractive or repulsive. The evolution of intera…
Minorities in a model for opinion formation
M. F. Laguna, Guillermo Abramson, Damian H. Zanette
We study a model for social influence in which the agents' opinion is a continuous variable [G. Weisbuch et al., Complexity \textbf{7}, 2, 55 (2002)]. The convergent opinion adjust…
Vector opinion dynamics in a model for social influence
M. F. Laguna, Guillermo Abramson, Damian H. Zanette
We present numerical simulations of a model of social influence, where the opinion of each agent is represented by a binary vector. Agents adjust their opinions as a result of rand…
Dynamical clustering in oscillator ensembles with time-dependent interactions
Damian H. Zanette, Alexander S. Mikhailov
We consider an ensemble of coupled oscillators whose individual states, in addition to the phase, are characterized by an internal variable with autonomous evolution. The time scal…
A note on non-thermodynamical applications of non-extensive statistics
Damian H. Zanette, Marcelo M. Montemurro
It is pointed out that the constraint to be imposed to the maximization of the entropy for processes outside the class of thermodynamical systems, is generally not well defined. In…
Dynamics of text generation with realistic Zipf distribution
Damián H. Zanette, Marcelo A. Montemurro
We investigate the origin of Zipf's law for words in written texts by means of a stochastic dynamical model for text generation. The model incorporates both features related to the…
Thermal measurements of stationary nonequilibrium systems: A test for generalized thermostatistics
Damian H. Zanette, Marcelo A. Montemurro
We show that a gas thermometer in contact with a stationary classical system out of thermal (Boltzmann) equilibrium evolves, under very general conditions, towards a state characte…
Dynamics and nonequilibrium states in the Hamiltonian mean-field model: A closer look
Damian H. Zanette, Marcelo A. Montemurro
We critically revisit the evidence for the existence of quasistationary states in the globally coupled XY (or Hamiltonian mean-field) model. A slow-relaxation regime at long times…
Non-monotonic dependence on disorder in biased diffusion on small-world networks
Damian H. Zanette
We report numerical simulations of a strongly biased diffusion process on a one-dimensional substrate with directed shortcuts between randomly chosen sites, i.e. with a small-world…
At the boundary between biological and cultural evolution: The origin of surname distributions
Susanna C. Manrubia, Damian H. Zanette
Surnames and nonrecombining alleles are inherited from a single parent in a highly similar way. A simple birth-death model with mutations can accurately describe this process. Expo…
Dynamics of rumor propagation on small-world networks
Damian H. Zanette
We study the dynamics of an epidemic-like model for the spread of a rumor on a small-world network. It has been shown that this model exhibits a transition between regimes of local…
Effects of immunization in small-world epidemics
Damian H. Zanette, Marcelo Kuperman
The propagation of model epidemics on a small-world network under the action of immunization is studied. Although the connectivity in this kind of networks is rather uniform, a vac…
Entropic analysis of the role of words in literary texts
Marcelo A. Montemurro, Damian H. Zanette
Beyond the local constraints imposed by grammar, words concatenated in long sequences carrying a complex message show statistical regularities that may reflect their linguistic rol…
Criticality of rumor propagation on small-world networks
Damian H. Zanette
We show that a simple model for the propagation of a rumor on a small-world network exhibits critical behavior at a finite randomness of the underlying graph. The transition occurs…
Critical behavior of propagation on small-world networks
Damian H. Zanette
We report numerical evidence that an epidemic-like model, which can be interpreted as the propagation of a rumor, exhibits critical behavior at a finite randomness of the underlyin…
Structures and propagation in globally coupled systems with time delays
Damian H. Zanette
We consider an ensemble of globally coupled phase oscillators whose interaction is transmitted at finite speed. This introduces time delays, which make the spatial coordinates rele…
Statistical-thermodynamical foundations of anomalous diffusion
Damian H. Zanette
It is shown that Tsallis' generalized statistics provides a natural frame for the statistical-thermodynamical description of anomalous diffusion. Within this generalized theory, a…
