Laser experiments with single atoms and the test of basic physics Academic Article uri icon


  • The interaction of a single Rydberg atom with a single mode of the electromagnetic field and the resonance fluorescence of a single atomic ion stored in radio-frequency trap were investigated. In the former experiment, the quantum collapse and revival of the atomic inversion predicted by the Jaynes-Cummings model could be demonstrated for the first time. In the latter experiment, antibunching and sub-Poissonian photon statistics were detected in the fluorescent light. Furthermore the observation of the crystallization of few ions in a trap is described. Since the stored ions can be cooled by the laser light and heated by the radio frequency field of the trap, subsequent phase transitions could be observed. 1988.
