Irrelevance of information outflow in opinion dynamics models
Claudio Castellano, Romualdo Pastor-Satorras
The Sznajd model for opinion dynamics has attracted a large interest as a simple realization of the psychological principle of social validation. As its most salient feature, it ha…
Voter models on weighted networks
Andrea Baronchelli, Claudio Castellano, Romualdo Pastor-Satorras
We study the dynamics of the voter and Moran processes running on top of complex network substrates where each edge has a weight depending on the degree of the nodes it connects. F…
Griffiths phases in the contact process on complex networks
Géza Ódor, Róbert Juhász, Claudio Castellano +1
Dynamical processes occurring on top of complex networks have become an exciting area of research. Quenched disorder plays a relevant role in general dynamical processes and phase…
Asymptotic energy profile of a wavepacket in disordered chains
S. Lepri, R. Schilling, S. Aubry
We investigate the long time behavior of a wavepacket initially localized at a single site in translationally invariant harmonic and anharmonic chains with random interaction…
Socio-economic utility and chemical potential
Rémi Lemoy, Eric Bertin, Pablo Jensen
In statistical physics, the conservation of particle number results in the equalization of the chemical potential throughout a system at equilibrium. In contrast, the homogeneity o…
Thresholds for epidemic spreading in networks
Claudio Castellano, Romualdo Pastor-Satorras
We study the threshold of epidemic models in quenched networks with degree distribution given by a power-law. For the susceptible-infected-susceptible (SIS) model the activity thre…
