Single-photon atomic cooling.
We report the cooling of an atomic ensemble with light, where each atom scatters only a single photon on average. This is a general method that does not require a cycling transition and can be applied to atoms or molecules that are magnetically trapped. We discuss the application of this new approach to the cooling of hydrogenic atoms for the purpose of precision spectroscopy and fundamental te...
متن کاملSingle-photon molecular cooling
We propose a general method to cool the translational motion of molecules. Our method is an extension of single photon atomic cooling which was successfully implemented in our laboratory. Requiring a single event of absorption followed by a spontaneous emission, this method circumvents the need for a cycling transition and can be applied to any paramagnetic or polar molecule. In our approach, t...
متن کاملSingle-photon cooling in a wedge billiard
Single-photon cooling (SPC), noted for its potential as a versatile method for cooling a variety of atomic species, has recently been demonstrated experimentally. In this paper, we study possible ways to improve the performance of SPC by applying it to atoms trapped inside a wedge billiard. The main feature of the wedge billiard for atoms, also experimentally realized recently, is that the natu...
متن کاملOne-photon atomic cooling with an optical Maxwell demon valve
We discuss the relationship between recent proposals of ‘atom diodes’ or oneway 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.
