Anomalous diffusion, aging, and nonergodicity of scaled Brownian motion with fractional Gaussian noise: Overview of related experimental observations and models
How does a systematic time-dependence of the diffusion coefficient D (t) affect the ergodic
and statistical characteristics of fractional Brownian motion (FBM)? Here, we answer this …

The inspection paradox in stochastic resetting
The remaining travel time of a plane shortens with every minute that passes from its
departure, and a flame diminishes a candle with every second it burns. Such everyday …

Towards a robust criterion of anomalous diffusion
Anomalous-diffusion, the departure of the spreading dynamics of diffusing particles from the
traditional law of Brownian-motion, is a signature feature of a large number of complex soft …

Non-Gaussian displacements in active transport on a carpet of motile cells
R Großmann, LS Bort, T Moldenhawer, M Stange… - Physical Review Letters, 2024 - APS
We study the dynamics of micron-sized particles on a layer of motile cells. This cell carpet
acts as an active bath that propels passive tracer particles via direct mechanical contact. The …
