A two species trap for chromium and rubidium atoms
نویسندگان
چکیده
We realize a combined trap for bosonic chromium (Cr) and rubidium (Rb) atoms. First experiments focus on exploring a suitable loading scheme for the combined trap and on studies of new trap loss mechanisms originating from simultaneous trapping of two species. By comparing the trap loss from the Rb magneto-optical trap (MOT) in absence and presence of magnetically trapped ground state Cr atoms we determine the scattering cross section of σinelRbCr = 5.0 ± 4.0 · 10−18 m for light induced inelastic collisions between the two species. Studying the trap loss from the Rb magneto-optical trap induced by the Cr cooling-laser light, the photoionization cross section of the excited 5P3/2 state at an ionizing wavelength of 426 nm is measured to be σp = 1.1±0.3 ·10−21 m.

Lifetime measurement of the 6s level of rubidium
We present a lifetime measurement of the 6s level of rubidium. We use a time-correlated single-photon counting technique on two different samples of rubidium atoms, a vapor cell with variable rubidium density, and a sample of atoms confined and cooled in a magneto-optical trap. The 5P1/2 level serves as the resonant intermediate step for the two-step excitation to the 6s level. We detect the de...

متن کاملTrap loss in a two-species Rb-Cs magneto-optical trap
During the past years, many experiments have been devoted to the study of excited-ground-state cold collisions using a sample of trapped cold atoms @1,2#. Recently, there has been greater interest in the study of collision mechanisms involving two different kinds of atoms in a mixed-species magneto-optical trap ~MOT! @3–9#. The nature of these collisions bears critically on matter-wave coherenc...
متن کاملLight-induced collisions of ultracold rubidium atoms
In this dissertation I present a variety of experiments on collisions between ultra-cold rubidium atoms. These collisions take place in light-force atom traps, where temperatures below 1 mK are reached. At these low temperatures weak, long-range interactions between the atoms are important, and collision times are long. Consequently, the absorption and spontaneous emission of photons plays an i...
متن کاملQuantum Degeneracy in an Atomic Fermi-Fermi-Bose Mixture
This thesis deals with dilute fermionic and bosonic quantum gases in the nK temperature regime. In the work presented here, the first quantum-degenerate mixture of two different fermionic atomic species and the first triple-degenerate Fermi-Fermi-Bose mixture were produced. The quantum-degenerate mixtures were realized using sympathetic cooling of the fermionic species 6Li and 40K by an evapora...
