Rhythmic behavior of an Ising Model with dissipation at low temperature
Raphael Cerf, Paolo Dai Pra, Marco Formentin +1
In this paper we consider the Glauber dynamics for the one-dimensional Ising model with dissipation, in a mesoscopic regime obtained by letting inverse temperature and volume go to…
Upscaling human activity data: an ecological perspective
Anna Tovo, Samuele Stivanello, Amos Maritan +3
In recent years we have witnessed an explosion of data collected for different human dynamics, from email communication to social networks activities. Extract useful information fr…
Oscillatory behavior in a model of non-Markovian mean field interacting spins
Paolo Dai Pra, Marco Formentin, Guglielmo Pelino
We analyze a non-Markovian mean field interacting spin system, related to the Curie--Weiss model. We relax the Markovianity assumption by replacing the memoryless distribution of t…
A hierarchical mean field model of interacting spins
Paolo Dai Pra, Marco Formentin, Guglielmo Pelino
We consider a system of hierarchical interacting spins under dynamics of spin-flip type with a ferromagnetic mean field interaction, scaling with the hierarchical distance, coupled…
Application of optimal data-based binning method to spatial analysis of ecological datasets
Anna Tovo, Marco Formentin, Marco Favretti +1
Investigation of highly structured data sets to unveil statistical regularities is of major importance in complex system research. The first step is to choose the scale at which to…
Collective periodicity in mean-field models of cooperative behavior
Francesca Collet, Paolo Dai Pra, Marco Formentin
We propose a way to break symmetry in stochastic dynamics by introducing a dissipation term. We show in a specific mean-field model, that if the reversible model undergoes a phase…
