Observation of Interactions between Trapped Ions and Ultracold Rydberg Atoms.

摘要: We report on the observation of interactions between ultracold Rydberg atoms and ions in a Paul trap. The rate observed inelastic collisions, which manifest themselves as charge transfer ions, exceeds that Langevin collisions for ground state by about 3 orders magnitude. This indicates huge increase interaction strength. study effect vacant trap's electric fields excitation spectra. To quantitatively describe exhibited shape ion loss spectra, we need to include ion-induced Stark shift atoms. Furthermore, demonstrate dipole-forbidden transition with aid field single trapped ion. Our results confirm can be controlled laser coupling states. Adding dynamic dressing may allow creation spin-spin elimination collisional heating due ionic micromotion atom-ion mixtures.
