Unravelling the origins of anomalous diffusion: from molecules to migrating storks

O Vilk, E Aghion, T Avgar, C Beta, O Nagel, A Sabri… - Physical Review …, 2022 - APS
Anomalous diffusion or, more generally, anomalous transport, with nonlinear dependence of
the mean-squared displacement on the measurement time, is ubiquitous in nature. It has …

[HTML][HTML] Record ages of non-Markovian scale-invariant random walks

L Régnier, M Dolgushev, O Bénichou - Nature Communications, 2023 - nature.com
How long is needed for an observable to exceed its previous highest value and establish a

Time scales in the dynamics of political opinions and the voter model

PG Meyer, R Metzler - New Journal of Physics, 2024 - iopscience.iop.org
Opinions in human societies are measured by political polls on time scales of months to
years. Such opinion polls do not resolve the effects of individual interactions but constitute a …

Inferring nonlinear fractional diffusion processes from single trajectories

JA Kassel, B Walter, H Kantz - New Journal of Physics, 2023 - iopscience.iop.org
We present a method to infer the arbitrary space-dependent drift and diffusion of a nonlinear
stochastic model driven by multiplicative fractional Gaussian noise from a single trajectory …

Trend analysis in the presence of short-and long-range correlations with application to regional warming

ET Phillips, M Höll, H Kantz, Y Zhou - Physical Review E, 2023 - APS
Many real-world time series exhibit both significant short-and long-range temporal
correlations. Such correlations enhance the errors of linear trend analysis. In this paper, we …
