The mean-square displacement (MSD) is widely utilized to study the dynamical properties of stochastic processes. The time-averaged MSD (TAMSD) provides some information on the …
We examine renewal processes with power-law waiting time distributions (WTDs) and non- zero drift via computing analytically and by computer simulations their ensemble and time …
We study a method for detecting the origins of anomalous diffusion, when it is observed in an ensemble of times-series, generated experimentally or numerically, without having …
With subrecoil-laser-cooled atoms, one may reach nanokelvin temperatures while the ergodic properties of these systems do not follow usual statistical laws. Instead, due to an …
We propose an analytical method to determine the shape of density profiles in the asymptotic long-time limit for a broad class of coupled continuous-time random walks which …
We report on a fundamental role of a non-normalized formal steady state, ie, an infinite invariant density, in a semi-Markov process where the state is determined by the interevent …

We provide analytical results for the ensemble-averaged and time-averaged squared displacement, and the randomness of the latter, in the full two-dimensional parameter space …
We consider the Langevin equation with dichotomously fluctuating diffusivity, where the diffusion coefficient changes dichotomously over time, in order to study fluctuations of time …
In recent years it was shown both theoretically and experimentally that in certain systems exhibiting anomalous diffusion the time-and ensemble-averaged mean-squared …
