Raman Sideband Cooling in presence of Multiple Decay Channels
G. Morigi, H. Baldauf, W. Lange +1
We have investigated the efficiency of pulsed Raman sideband cooling in the presence of multiple decay and excitation channels. By applying sum rules we identify parameter regimes…
Absolute frequency measurement of the In clock transition with a mode-locked laser
J. von Zanthier, Th. Becker, M. Eichenseer +11
The absolute frequency of the In - clock transition at 237 nm was measured with an accuracy of 1.8 parts in . Using a phase-coherent…
Quantum Coherence in a Single Ion due to strong Excitation of a metastable Transition
J. von Zanthier, C. Skornia, G. S. Agarwal +1
We consider pump-probe spectroscopy of a single ion with a highly metastable (probe) clock transition which is monitored by using the quantum jump technique. For a weak clock laser…
Vacuum-Stimulated Raman Scattering based on Adiabatic Passage in a High-Finesse Optical Cavity
M. Hennrich, T. Legero, A. Kuhn +1
We report on the first observation of stimulated Raman scattering from a Lambda-type three-level atom, where the stimulation is realized by the vacuum field of a high-finesse optic…
A feasible "Kochen-Specker" experiment with single particles
Christoph Simon, Marek Zukowski, Harald Weinfurter +1
We present a simple experimental scheme which can be used to demonstrate an all-or-nothing type contradiction between non-contextual hidden variables and quantum mechanics. The sch…
Experiments towards Falsification of Noncontextual Hidden Variable Theories
Markus Michler, Harald Weinfurter, Marek Zukowski
We present two experiments testing the hypothesis of noncontextual hidden variables (NCHV's). The first one is based on observation of two-photon pseudo-Greenberger-Horne-Zeilinger…
