A single atom localised in the mode of a high-finesse cavity is a highly interesting system. For example it allows one to investigate the dynamics of a continuously observed quantum system. Moreover, fascinating applications in quantum-information processing and quantum computing are expected. However, the experimental realisation of this system is extremely challenging.
Previous experiments succeeded in trapping a single atom in the far-detuned mode of a cavity . However the storage time is short and limited by heating from fluctuations of the intracavity light field. But, using the velocity-dependent forces predicted for a strongly-coupled atom-cavity system , it should be possible to cool the motion of the atom in the cavity. Extending the work of , where heating from velocity-dependent forces was observed, we now investigate cavity-mediated cooling for extending the storage time of a single atom in the cavity.
