An Overview of Generalized Gamma Mittag–Leffler Model and Its Applications
Axioms, 2015 Recently, probability models with thicker or thinner tails have gained more importance among statisticians and physicists because of their vast applications in random walks, Lévi flights, financial modeling, etc.

Superstatistical generalised Langevin equation: non-Gaussian viscoelastic anomalous diffusion
New Journal of Physics, 2018 Recent advances in single particle tracking and supercomputing techniques demonstrate the emergence of normal or anomalous, viscoelastic diffusion in conjunction with non-Gaussian distributions in soft, biological, and active matter systems.

Stability of the entropy for superstatistics [PDF]
Physics Letters A, 2003 The Boltzmann-Gibbs celebrated entropy $S_{BG}=-k\sum_ip_i \ln p_i$ is {\it concave} (with regard to all probability distributions $\{p_i\}$) and {\it stable} (under arbitrarily small deformations of any given probability distribution). It seems reasonable to consider these two properties as {\it necessary} for an entropic form to be a {\it physical ...

Superstatistics in hydrodynamic turbulence [PDF]
Physica D: Nonlinear Phenomena, 2004 Superstatistics is a `statistics of a statistics' relevant for driven nonequilibrium systems with fluctuating intensive parameters. It contains Tsallis statistics as a special case. We show that the probability density functions of velocity differences and accelerations measured in Eulerian and Lagrangian turbulence experiments are well reproduced by ...

New Journal of Physics, 2019 Many studies on biological and soft matter systems report the joint presence of a linear mean-squared displacement and a non-Gaussian probability density exhibiting, for instance, exponential or stretched-Gaussian tails.

Anomalous Dynamics of Colloids and Their Cluster Formation in Active Liquids [PDF]
EPJ Web of ConferencesWe examine the dynamics of individual colloidal particles in active media. Unlike Brownian particles, which display a Gaussian distribution in displacement, the colloids in active media show deviations from this form.

Atmospheric turbulence and superstatistics [PDF]
Europhysics News, 2005 Nonequilibrium systems with large-scale fluctuations of a suitable system parameter are often effectively described by a superposition of two statistics, a superstatistics. Here we illustrate this concept by analysing experimental data of fluctuations in atmospheric wind velocity differences at Florence airport.
