Article: Photon correlation versus interference of single-atom fluorescence in a half-cavity.
[show abstract] [hide abstract]
ABSTRACT: Photon correlations are investigated for a single laser-excited ion trapped in front of a mirror. Varying the relative distance between the ion and the mirror, photon correlation statistics can be tuned smoothly from an antibunching minimum to a bunchinglike maximum. Our analysis concerns the non-Markovian regime of the ion-mirror interaction and reveals the field establishment in a half-cavity interferometer.Physical Review Letters 06/2007; 98(18):183003. · 7.37 Impact Factor -

Article: Feedback cooling of a single trapped ion.
[show abstract] [hide abstract]
ABSTRACT: Based on a real-time measurement of the motion of a single ion in a Paul trap, we demonstrate its electromechanical cooling below the Doppler limit by homodyne feedback control (cold damping). The feedback cooling results are well described by a model based on a quantum mechanical master equation.Physical Review Letters 03/2006; 96(4):043003. · 7.37 Impact Factor
