Chaos in the Hamiltonian mean field model
Francesco Ginelli, Kazumasa A. Takeuchi, Hugues Chate' +2
We study the dynamical properties of the canonical ordered phase of the Hamiltonian mean-field (HMF) model, in which particles, globally-coupled via pairwise attractive interac…
Coherent periodic activity in excitatory Erdos-Renyi neural networks:The role of network connectivity
Lorenzo Tattini, Simona Olmi, Alessandro Torcini
We consider an excitatory random network of leaky integrate-and-fire pulse coupled neurons. The neurons are connected as in a directed Erdös-Renyi graph with average connectivity $…
Extensive and Sub-Extensive Chaos in Globally-Coupled Dynamical Systems
Kazumasa A. Takeuchi, Hugues Chaté, Francesco Ginelli +2
Using a combination of analytical and numerical techniques, we show that chaos in globally-coupled identical dynamical systems, be they dissipative or Hamiltonian, is both extensiv…
Discrete Breathers in a Realistic Coarse-Grained Model of Proteins
S. Luccioli, A. Imparato, S. Lepri +2
We report the results of molecular dynamics simulations of an off-lattice protein model featuring a physical force-field and amino-acid sequence. We show that localized modes of no…
