The interaction strength was chosen linearly spaced and the simulation
results are presented in \cref{fig:delta_energy_overview}.
As the shape of the BCF is not altered between the simulations, the
bath energy flows look very similar as do the interaction
energies. The main difference between the simulations is the magnitude
of the interaction energy. With increased coupling strength there is
an increased interaction energy and an increased flow which leads to
faster energy loss in the system and faster energy gain of the
bath. The stronger the coupling, the more pronounced is the
non-monotonicity in time of the interaction energy, which is reflected
in a non-monotonicity in the bath energy expectation value.
The bath energy reaches a maximum and falls slightly for the strongest
coupling simulations. If the interaction is strong enough,
``backflow'' can occur despite finite bath correlation times. In
\cref{fig:markov_analysis_steady} the bath memory is long,
additionally to a strong coupling so that multiple oscillations can be
seen.
