Description
We examine non-Markovian effects in an open quantum system
from the point of view of information flow. To this end, we
consider the spin-boson model with a cold reservoir,
accounting for the exact time-dependent correlations between
the system and the bath to study the exchange of information
and heat. We use an information theoretic measure of the
relevant memory effects and demonstrate that the information
backflow from the reservoir to the system does not
necessarily correlate with the backflow of heat. We also
examine the influence of temperature and coupling strength
on the loss and gain of information between the system and
the bath. Finally, we discuss how additional driving changes
the backflow of information, giving rise to potential
applications in reservoir engineering.
