  • Bose-Einstein Condensation of 84Sr 

    Martinez de Escobar, Y.N.; Mickelson, P.G.; Yan, M.; DeSalvo, B.J.; Nagel, S.B.; Killian, T.C. (2009-11-09)
    We report Bose-Einstein condensation of Sr84 in an optical dipole trap. Efficient laser cooling on the narrow intercombination line and an ideal s-wave scattering length allow the creation of large condensates (N0∼3×105) ...
  • Bose-Einstein condensation of 88Sr through sympathetic cooling with 87Sr 

    Mickelson, P.G.; Martinez de Escobar, Y.N.; Yan, M.; DeSalvo, B.J.; Killian, T.C. (2010-05-05)
    We report Bose-Einstein condensation of Sr88, which has a small, negative s-wave scattering length (a88=−2a0). We overcome the poor evaporative cooling characteristics of this isotope by sympathetic cooling with Sr87 atoms. ...
  • Degenerate Fermi Gas of 87Sr 

    DeSalvo, B.J.; Yan, M.; Mickelson, P.G.; Martinez de Escobar, Y.N.; Killian, T.C. (2010-07-13)
    We report quantum degeneracy in a gas of ultracold fermionic Sr87 atoms. By evaporatively cooling a mixture of spin states in an optical dipole trap for 10.5 s, we obtain samples well into the degenerate regime with ...
  • Inelastic and elastic collision rates for triplet states of ultracold strontium 

    Traverso, A.; Chakraborty, R.; Martinez de Escobar, Y.N.; Mickelson, P.G.; Nagel, S.B.; Yan, M.; Killian, T.C. (2009-06-05)
  • Numerical modeling of collisional dynamics of Sr in an optical dipole trap 

    Yan, M.; Chakraborty, R.; Mazurenko, A.; Mickelson, P.G.; Martinez de Escobar, Y.N.; DeSalvo, B.J.; Killian, T.C. (2011-03-09)
    We describe a model of inelastic and elastic collisional dynamics of atoms in an optical dipole trap that utilizes numerical evaluation of statistical mechanical quantities and numerical solution of equations for the ...
  • Two-photon photoassociative spectroscopy of ultracold 88Sr 

    Martinez de Escobar, Y.N.; Mickelson, P.G.; Pellegrini, P.; Nagel, S.B.; Traverso, A.; Yan, M.; Cote, R.; Killian, T.C. (2008-12-10)
