Abstract
We present measurements of interspecies thermalization between ultracold samples of 133Cs and either 174Yb or 170Yb. The two species are trapped in a far-off-resonance optical dipole trap and 133Cs is sympathetically cooled by Yb. We extract effective interspecies thermalization cross sections by fitting the thermalization measurements to a kinetic model, giving σCs174Yb = (5 ± 2) × 10−13 cm2 and σCs170Yb = (18 ± 8) × 10−13 cm2. We perform quantum scattering calculations of the thermalization cross sections and optimize the CsYb interaction potential to reproduce the measurements. We predict scattering lengths for all isotopic combinations of Cs and Yb. We also demonstrate the independent production of 174Yb and 133Cs Bose-Einstein condensates using the same optical dipole trap, an important step toward the realization of a quantum-degenerate mixture of the two species.
