Tracing non-equilibrium signatures in time series obtained from biological systems — •Samuel Salinas-Almaguer, Florian Rehfeldt, and Matthias Weiss — Experimentalphysik I, Universität Bayreuth

Revealing whether a stationary time series originated from an out-of-equilibrium system is, in general, a non-trivial task. While living biological systems surely are far away from thermal equilibrium, this might not be directly visible in a given experimentally acquired time series of some accessible observables. Therefore, probing whether time reversibility and detailed balance are broken in such time series, and quantifying a putative net entropy production is mandatory in the analysis. Using analytical and numerical toy systems as well as experimental data acquired in living cells, we compare different methods to uncover and quantify the non-equilibrium nature of time series.
