Measurement of collisions between rubidium atoms and optically dark rubidium ions
Seunghyun Lee, K. Ravi, S. A. Rangwala
We measure the collision rate coefficient between laser cooled Rubidium (Rb) atoms in a magneto-optical trap (MOT) and optically dark Rb+ ions in an overlapping Paul trap. In such…
Sympathetic and swap cooling of trapped ions by cold atoms in a MOT
K. Ravi, Seunghyun Lee, Arijit Sharma +2
A mixed system of cooled and trapped, ions and atoms, paves the way for ion assisted cold chemistry and novel many body studies. Due to the different individual trapping mechanisms…
Combined ion and atom trap for low temperature ion-atom physics
K. Ravi, Seunghyun Lee, Arijit Sharma +2
We report an experimental apparatus and technique which simultaneously traps ions and cold atoms with spatial overlap. Such an apparatus is motivated by the study of ion-atom proce…
A Three Dimensional Lattice of Ion Traps
K. Ravi, Seunghyun Lee, Arijit Sharma +3
We propose an ion trap configuration such that individual traps can be stacked together in a three dimensional simple cubic arrangement. The isolated trap as well as the extended a…
Electric-field-induced change of alkali-metal vapor density in paraffin-coated cells
D. F. Jackson Kimball, Khoa Nguyen, K. Ravi +6
Alkali vapor cells with antirelaxation coating (especially paraffin-coated cells) have been a central tool in optical pumping and atomic spectroscopy experiments for 50 years. We h…
