Summary on Grant Application Form |

Trapped ions will be used for an experimental investigation into various phenomena in cavity QED which have hitherto only been seen using atomic beam sources, the advantage being the elimination of classical fluctuations. We will develop planar traps small enough to insert into an optical cavity and use such a trap to observe the normal mode splitting for a small ensemble of ions held in the cavity. We will do this by measuring the cavity ring-down signal when the intracavity field is switched between 'high' and low power. This signal is expected to show oscillations at a frequency given by the normal mode splitting. We will use practically the same apparatus to measure the second order correlation function of the light transmitted by the coupled ion-ensemble/cavity system. This function is expected to display strong anti-bunching and sub-Poissonian statistics. The visibility of these manifestly quantum effects should be greater for these experiments than for the analogous atomic beam experiments. Finally we will attempt to measure the normal mode splitting spectroscopically using a weak but independently tunable 313nm source which is currently under development.
