Mori-Zwanzig memory analysis in single-molecule spectroscopy

We study the dynamical behavior of the Rhodospirillum molischianum LH2 complex based on intensity time series obtained from single-molecule spectroscopy experiments. This is achieved by reconstructing the memory function describing the time-dependent fluctuations of the excited states. We conclude that the apparent stochastic evolution of the dynamics is controlled by at least two different non-Markovian main processes.
