Generalized Lyapunov exponents of the random harmonic oscillator: cumulant expansion approach
Raul Vallejos, Celia Anteneodo
The cumulant expansion is used to estimate generalized Lyapunov exponents of the random-frequency harmonic oscillator. Three stochastic processes are considered: Gaussian white noi…
Solution on the Bethe lattice of a hard core athermal gas with two kinds of particles
T. J. Oliveira, J. F. Stilck
Athermal lattice gases of particles with first neighbor exclusion have been studied for a long time as simple models exhibiting a fluid-solid transition. At low concentration the p…
Generalizing Planck's distribution by using the Carati-Galgani model of molecular collisions
R. D. B. Carvalho, A. M. C. Souza
Classical systems of coupled harmonic oscillators are studied using the Carati-Galgani model. We investigate the consequences for Einstein's conjecture by considering that the exch…
A scale-invariant probabilistic model based on Leibniz-like pyramids
Antonio Rodríguez, Constantino Tsallis
We introduce a family of probabilistic {\it scale-invariant} Leibniz-like pyramids and -dimensional hyperpyramids (), characterized by a parameter , whose…
On exact time-averages of a massive Poisson particle
Welles A. M. Morgado, Silvio M. Duarte Queiros, Diogo O. Soares-Pinto
In this work we study, under the Stratonovich definition, the problem of the damped oscillatory massive particle subject to a heterogeneous Poisson noise characterised by a rate of…
Restricted random walk model as a new testing ground for the applicability of q-statistics
Ugur Tirnakli, Henrik J. Jensen, Constantino Tsallis
We present exact results obtained from Master Equations for the probability function P(y,T) of sums of the positions x_t of a discrete random walker restricted…
Non-parametric segmentation of non-stationary time series
S. Camargo, S. Duarte Queirós, C. Anteneodo
The non-stationary evolution of observable quantities in complex systems can frequently be described as a juxtaposition of quasi-stationary spells. Given that standard theoretical…
Anomalous diffusion in a symbolic model
H. V. Ribeiro, E. K. Lenzi, R. S. Mendes +1
We address this work to investigate some statistical properties of symbolic sequences generated by a numerical procedure in which the symbols are repeated following a power law pro…
Some Open Points in Nonextensive Statistical Mechanics
Constantino Tsallis
We present and discuss a list of some interesting points that are currently open in nonextensive statistical mechanics. Their analytical, numerical, experimental or observational a…
