Trapping an atom with single photons
Article Abstract:
It has been possible to develop high-finesse optical cavity experiments in which the change in transmission prompted by a single slow atom approaching the cavity sparks off an external feedback switch which traps the atom in a light field containing around one photon on average. The quantum character of the cavity field boosts the momentum diffusion compared with that in a coherent light field. This is attributable to the back action of the atom on the cavity field. A single particle trapped in a high-finesse cavity has applications in the rapidly expanding area of quantum communication.

Cavity cooling of a single atom
Article Abstract:
Alternative cooling methods are proposed for a single atom, strongly coupled to a high-finesse cavity. Such cooling schemes are useful to improve the performance of atom-cavity systems for quantum information processing.
