The Atom Diode and other laser-based control devices for cold atoms

In the first part, we present 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. In the second part, we propose laser-based devices which use tunneling resonances to select or prepare the velocity of cold atoms.
