Currents in complex polymers: an example of superstatistics for short time series

We apply superstatistical techniques to an experimental time series of measured transient current through a thin Aluminium-PMMA-Aluminium film. We show that in good approximation the current can be approximated by local Gaussian processes with fluctuating variance. The marginal density exhibits `fat tails' and is well modelled by a superstatistical model. Our techniques can be generally applied to other short time series as well.
