Atom diode: A laser device for a unidirectional transmission of ground-state atoms — •Andreas Ruschhaupt — Institut für Mathematische Physik, TU Braunschweig, Mendelssohnstr. 3, D-38106 Braunschweig, Germany

We propose and discuss different schemes for an “atom diode”, namely, a one-dimensional laser device that lets a two or three-level ground state atom pass in one direction, say from left to right, but not in the opposite direction. A new method for cooling atoms or molecules based on the atom diode is presented.
