When low-order expansions fail and all higher-order contributions matter—basic example of the mean squared displacement for brownian motion

HIGHLIGHTS

• who: Andreas M. Menzel from the Institut fuu0308r Physik, Otto-von-Guericke-Universitau0308t Magdeburg, Universitau0308tsplatz, Magdeburg, Germany have published the paper: When low-order expansions fail and all higher-order contributions matteru2014basic example of the mean squared displacement for Brownian motion, in the Journal: Eur. Phys. J. E (2022) 45 :77 of /2022/
• what: The authors show in Sect 3 that a lowest-order expansion in time fails to predict the linear, diffusive time dependence of the mean squared displacement. Subsequently, the authors demonstrate in Sect 4 how the addition of all higherorder contributions restores . . .
