AC-Stark shift and photoionization of Rydberg atoms in an optical dipole trap
AC-Stark shift photoionization Rydberg atoms
2010/11/12
We have measured the AC-Stark shift of the $14D_{5/2}$ Rydberg state of rubidium 87 in an optical dipole trap formed by a focussed CO$_2$-laser. We find good quantitative agreement with the model of ...
Researchers in Switzerland have demonstrated an innovative way of trapping tiny objects using electrostatic fields. The device could allow scientists to scrutinize much smaller biological molecules th...
Single Cs Atoms as Collisional Probes in a large Rb Magneto-Optical Trap
Single Cs Atoms Collisional Probes a large Rb Magneto-Optical Trap
2010/10/29
We study cold inter-species collisions of Caesium and Rubidium in a strongly imbalanced system with single and few Cs atoms. Observation of the single atom fuorescence dynamics yields insight into lig...
