We present a compact, transportable system that produces Bose–Einstein condensates near the surface of an integrated atom microchip. The system occupies a volume of 0.4 m3, operates at a repetition rate as high as 0.3 Hz, and consumes an average power of 525 W. Evaporative cooling in a chip trap with trap frequencies of several kilohertz leads to nearly pure condensates containing 1.9×10487Rb atoms. Partial condensates are observed at a temperature of 1.58(8) μK, close to the theoretical transition temperature of 1.1 μK.

    Abstract. We present two all-optical approaches based on dipole force traps to prepare quantum-degenerate gases. Evaporative cooling in a gravito-optical surface trap is discussed as a prospective way to create a Bose-Einstein condensate of cesium and a two-dimensional quantum gas. Sympathetic...

    We describe the realization of Bose-Einstein condensates (BEC) of 87Rb atoms with relatively large number of atoms at high density, in laser-optical traps in our laboratory. Starting from a giant magneto-optical trap containing nearly 1010 atoms, we transfer about 5 x 107 atoms into the optical...

    In this article we review our recent experiments with a 40K-87Rb mixture. We demonstrate rapid sympathetic cooling of a 40K-87Rb mixture to dual quantum degeneracy on an atom chip. We also provide details on efficient BEC production, species-selective magnetic confinement, and progress toward...
