Lévy walks

V Zaburdaev, S Denisov, J Klafter - Reviews of Modern Physics, 2015 - APS
Random walk is a fundamental concept with applications ranging from quantum physics to
econometrics. Remarkably, one specific model of random walks appears to be ubiquitous …

Non-additive entropies and statistical mechanics at the edge of chaos: a bridge between natural and social sciences

C Tsallis - … Transactions of the Royal Society A, 2023 - royalsocietypublishing.org
The Boltzmann–Gibbs (BG) statistical mechanics constitutes one of the pillars of

Diffusion with resetting in a logarithmic potential

S Ray, S Reuveni - The Journal of chemical physics, 2020 - pubs.aip.org
We study the effect of resetting on diffusion in a logarithmic potential. In this model, a particle
diffusing in a potential U (x)= U 0 log| x| is reset, ie, taken back to its initial position, with a …

Entropy

C Tsallis - Encyclopedia, 2022 - mdpi.com
Definition The concept of entropy constitutes, together with energy, a cornerstone of
contemporary physics and related areas. It was originally introduced by Clausius in 1865 …

The standard map: From Boltzmann-Gibbs statistics to Tsallis statistics

U Tirnakli, EP Borges - Scientific reports, 2016 - nature.com
Abstract As well known, Boltzmann-Gibbs statistics is the correct way of thermostatistically
approaching ergodic systems. On the other hand, nontrivial ergodicity breakdown and …

From the area under the Bessel excursion to anomalous diffusion of cold atoms

E Barkai, E Aghion, DA Kessler - Physical Review X, 2014 - APS
Lévy flights are random walks in which the probability distribution of the step sizes is fat-
tailed. Lévy spatial diffusion has been observed for a collection of ultracold Rb 87 atoms and …

Neural complexity through a nonextensive statistical–mechanical approach of human electroencephalograms

DM Abramov, C Tsallis, HS Lima - Scientific Reports, 2023 - nature.com
The brain is a complex system whose understanding enables potentially deeper
approaches to mental phenomena. Dynamics of wide classes of complex systems have …

[HTML][HTML] Dynamics in fractal spaces

E Megías, AK Golmankhaneh, A Deppman - Physics Letters B, 2024 - Elsevier
This study investigates the interconnections between the traditional Fokker-Planck Equation
