State-selected rubidium-87 molecules were created at rest in a dilute Bose-Einstein condensate of rubidium-87 atoms with coherent free-bound stimulated Raman transitions. The transition rate exhibited a resonance line shape with an extremely narrow width as small as 1.5 kilohertz. The precise shape and position of the resonance are sensitive to the mean-field interactions between the molecules ...

We report on the generation of more than 5 dB of vacuum squeezed light at the Rubidium D1 line (795 nm) using periodically poled KTiOPO 4 (PPKTP) in an optical parametric oscillator. We demonstrate squeezing at low sideband frequencies, making this source of non-classical light compatible with bandwidth limited atom optics experiments. When PPKTP is operated as a parametric amplifier, we show a...

We study the enhancement and suppression of different multi-waving mixing (MWM) processes in a Rydberg-EIT rubidium vapor system both theoretically and experimentally. The nonlinear dispersion property of hot rubidium atoms is modulated by the Rydberg-Rydberg interaction, which can result in a nonlinear phase shift of the relative phase between dark and bright states. Such Rydberg-induced nonli...

Many atomic physics laboratories rely on beams of alkali atoms for their experiments, for example in the atom optics and laser cooling communities. Rubidium is commonly used, due to the fortunate coincidence of the dipole resonant transition with the optimum output wavelength of low-cost AlGaAs semiconductor lasers. Suitable rubidium beams can easily be produced with effusive ovens, but many ex...

We present direct ESI Q-TOF MS and X-ray evidence for remarkable structural and metal ion size effects on the formation of thymidine-based T-tetramers. The conventional H-bond acceptors on the ribose and deoxyribose may disfavor the formation of T-tetramers, and in the series of alkali metal ions, lithium did not induce T-tetramer due to its small ion size. Sodium, potassium, rubidium and caesi...

We describe the properties of mixtures composed by potassium and rubidium atoms, simultaneously trapped in a magnetic potential. Potassium isotopes are cooled down to quantum degeneracy by means of sympathetic cooling with rubidium [1]. We can produce both a two-species Bose-Einstein condensate [2] mixing together Rb and K, and a degenerate system composed by a Fermi gas of K atoms and a Bose-E...
