Query: Fermionic reaction coordinates and their application to an autonomous
  Maxwell demon in the strong coupling regime   We establish a theoretical method which goes beyond the weak coupling and
Markovian approximations while remaining intuitive, using a quantum master
equation in a larger Hilbert space. The method is applicable to all impurity
Hamiltonians tunnel-coupled to one (or multiple) baths of free fermions. The
accuracy of the method is in principle not limited by the system-bath coupling
strength, but rather by the shape of the spectral density and it is especially
suited to study situations far away from the wide-band limit. In analogy to the
bosonic case, we call it the fermionic reaction coordinate mapping. As an
application we consider a thermoelectric device made of two Coulomb-coupled
quantum dots. We pay particular attention to the regime where this device
operates as an autonomous Maxwell demon shoveling electrons against the voltage
bias thanks to information. Contrary to previous studies we do not rely on a
Markovian weak coupling description. Our numerical findings reveal that in the
regime of strong coupling and non-Markovianity, the Maxwell demon is often
doomed to disappear except in a narrow parameter regime of small power output.
