Fast collective oscillations and clustering phenomena in an antiferromagnetic mean-field model
Arthur Vesperini, Roberto Franzosi, Stefano Ruffo +2
We study the out-of-equilibrium properties of the antiferromagnetic Hamiltonian Mean-Field model at low energy. In this regime, the Hamiltonian dynamics exhibits the presence of a…
Slowing down of so-called chaotic states: "Freezing" the initial state
Martin Belger, Sarah De Nigris, Xavier Leoncini
The so-called chaotic states that emerge on the model of interacting on regular critical range networks are analyzed. Typical time scales are extracted from the time series an…
Emergence of a collective crystal in a classical system with long-range interactions
Alessio Turchi, Duccio Fanelli, Xavier Leoncini
A one-dimensional long-range model of classical rotators with an extended degree of complexity, as compared to paradigmatic long-range systems, is introduced and studied. Working a…
Critical behaviour of the XY -rotors model on regular and small world networks
Sarah De Nigris, Xavier Leoncini
We study the XY-rotors model on small networks whose number of links scales with the system size , where . We first focus on regular one dimensional r…
Emergence of a non trivial fluctuating phase in the XY model on regular networks
Sarah De Nigris, Xavier Leoncini
We study an XY-rotor model on regular one dimensional lattices by varying the number of neighbours. The parameter is defined. corresponds to mean field and …
Statistical theory of quasi stationary states beyond the single water-bag case study
Mallbor Assllani, Duccio Fanelli, Alessio Turchi +2
An analytical solution for the out-of-equilibrium quasi-stationary states of the paradigmatic Hamiltonian Mean Field (HMF) model can be obtained from a maximum entropy principle. T…
