  An approach based on a non-Markovian time-convolutionless polaron master
equation is used to probe the quantum dynamics of a chromophore-qubit in a
super-Ohmic bath. Utilizing a measure of non-Markovianity based on dynamical
fixed points, we study the effects of the environment temperature and the
coupling strength on the non-Markovian behavior of the chromophore in a
super-Ohmic bath. It is found that an increase in the temperature results in a
reduction in the backflow information from the environment to the chromophore,
and therefore, a suppression of non-Markovianity. In the weak coupling regime,
increasing coupling strength will enhance the non- Markovianity, while the
effect is reversed in the strong coupling regime.
