Breakdown of Exponential Sensitivity to Initial Conditions: Role of the Range of Interactions

Within a microcanonical scenario we numerically study an N-sized linear chain classical inertial XY model including ferromagnetic couplings which decrease with distance as r (a $ 0). We show that for…

A generalized stochastic model with the property known as mean reversion, that is, the tendency to relax towards a historical reference level, is investigated and it is shown that additive-multiplicative processes provide realistic models to describe empirical distributions, for the whole range of data.

Role of the range of the interactions in thermal conduction.

It is found that Fourier's law, as signaled by a finite κ in the thermodynamic limit, holds only for sufficiently short-range interactions, with α>α_{c}(T).
Poissonian bursts in e-mail correspondence

- 7 July 2009
This work uses the Fano and Allan factors to quantify the extent to which the empirical data are more correlated — bursty — than a Poisson process, demonstrating that any correlations in the data are not due to the precise ordering of events.
Diffusive anomalies in a long-range Hamiltonian system.

It is shown that diffusive motion in quasistationary trajectories depends strongly on system size, and from the analysis of the second moment of numerical distributions, the relaxation to equilibrium is discussed.
Bridging stylized facts in finance and data non-stationarities

Employing a recent technique which allows the representation of nonstationary data by means of a juxtaposition of locally stationary paths of different length, we introduce a comprehensive analysis…
How does public opinion become extreme?
An activation model of opinion dynamics with interaction rules based on the existence of individual “stubbornness” that mimics empirical observations is proposed and represents an early-warning signal to forecast the transition from moderate to extreme views.
