One-photon atomic cooling with an optical Maxwell demon valve

We discuss the relationship between recent proposals of 'atom diodes' or one-way barriers for ultracold atoms and a Maxwell demon valve: in particular the way in which these proposals make use of dissipation via a one-photon spontaneous emission and avoid violation of the second law.
