Description
n the talk I will discuss motion in an environment, where
each location only allows motion at random discrete time
points separated by power law distributed random time
intervals. As an example one can think of a network of bus
or train routes with erratic arrival times. We find that for
heavy-tailed power laws the motion through the environment
becomes logarithmicly slow. Surprisingly the uncertainty in
the location grows slower than the relative position.
The original motivation of the work was the study of single
files of subdiffusive continuous time random walkers. In the
talk I will present scaling arguments for the mean square
displacement of a tagged particle in such a file.
