- Abstract: The second law of thermodynamics prohibits spontaneous heat from a cold to a
hot body. However, it has been theoretically and experimentally shown that
energy can flow from a cold to a hot body if the bodies are initially
correlated. We investigated the \emph{anomalous energy exchange} between
dissipation-less quantum systems that are initially entangled. Then, we
extended this model to include dissipation demonstrating \emph{anomalous heat}
from a cold to a hot body. Based on these models, we constructed a heat pump
driven entirely by quantum correlation as fuel and investigated its performance
with numerical simulations. Using the recently proposed definition of
efficiency based on mutual information, the performance of the pump is found to
be consistent with the second law of thermodynamics.

In classical thermodynamics energy always flows from the hotter system to the colder one.
If these systems are initially correlated, the energy flow can reverse, making the cold system colder and the hot system hotter.
This intriguing phenomenon is called anomalous energy flow'' and shows the importance of initial correlations in determining physical properties of thermodynamic systems.

We consider adiabatic quantum pumping through a resonant level model, a single-level quantum dot connected to two fermionic leads.
We develop a self-contained thermodynamic description of this model accounting for the variation of the energy level of the dot and the tunnelling rates with the thermal baths.
