Random diffusivity from stochastic equations: comparison of two models for Brownian yet non-Gaussian diffusion
V. Sposini, A. V. Chechkin, F. Seno +2
A considerable number of systems have recently been reported in which Brownian yet non-Gaussian dynamics was observed. These are processes characterised by a linear growth in time…
First passage statistics for diffusing diffusivity
V. Sposini, A. V. Chechkin, R. Metzler
A rapidly increasing number of systems is identified in which the stochastic motion of tracer particles follows the Brownian law yet the d…
Finite-energy Lévy-type motion through heterogeneous ensemble of Brownian particles
Oleksii Yu. Sliusarenko, Silvia Vitali, Vittoria Sposini +4
Complex systems display anomalous diffusion, whose signature is a space/time scaling with in the Probability Density Function (PDF). Anomalous diffusion can…
Langevin equation in complex media and anomalous diffusion
Silvia Vitali, Vittoria Sposini, Oleksii Sliusarenko +3
The problem of biological motion is a very intriguing and topical issue. Many efforts are being focused on the development of novel modeling approaches for the description of anoma…
Centre-of-mass like superposition of Ornstein-Uhlenbeck processes: a pathway to non-autonomous stochastic differential equations and to fractional diffusion
Mirko D'Ovidio, Silvia Vitali, Vittoria Sposini +4
We consider an ensemble of Ornstein-Uhlenbeck processes featuring a population of relaxation times and a population of noise amplitudes that characterize the heterogeneity of the e…
