Metastability in the Hamiltonian Mean Field model and Kuramoto model
Alessandro Pluchino, Andrea Rapisarda
We briefly discuss the state of the art on the anomalous dynamics of the Hamiltonian Mean Field model. We stress the important role of the initial conditions for understanding the…
Olami-Feder-Christensen Model on different Networks
Filippo Caruso, Vito Latora, Alessandro Pluchino +2
We investigate numerically the Self Organized Criticality (SOC) properties of the dissipative Olami-Feder-Christensen model on small-world and scale-free networks. We find that the…
Compromise and Synchronization in Opinion Dynamics
Alessandro Pluchino, Vito Latora, Andrea Rapisarda
We discuss two models of opinion dynamics. First wepresent a brief review of the Hegselmann and Krause (HK) compromise model in two dimensions, showing that it is possible to simul…
Glassy dynamics and nonextensive effects in the HMF model: the importance of initial conditions
Alessandro Pluchino, Andrea Rapisarda
We review the anomalies of the HMF model and discuss the robusteness of the glassy features vs the initial conditions. Connections to Tsallis statistics are also addressed.
Effective spin-glass Hamiltonian for the anomalous dynamics of the HMF model
Alessandro Pluchino, Vito Latora, Andrea Rapisarda
We discuss an effective spin-glass Hamiltonian which can be used to study the glassy-like dynamics observed in the metastable states of the Hamiltonian Mean Field (HMF) model. By m…
Vector Opinion Dynamics in a Bounded Confidence Consensus Model
Santo Fortunato, Vito Latora, Alessandro Pluchino +1
We study the continuum opinion dynamics of the compromise model of Krause and Hegselmann for a community of mutually interacting agents, by solving numerically a rate equation. The…
