Heteronuclear quantum gas mixtures
C. Ospelkaus, S. Ospelkaus
This PhD tutorial article is a review of our experiments on heteronuclear quantum gas mixtures at the University of Hamburg. We introduce basic properties of trapped Fermi-Bose mix…
Heteronuclear molecules in an optical dipole trap
J. J. Zirbel, K. -K. Ni, S. Ospelkaus +6
We report on the creation and characterization of heteronuclear KRb Feshbach molecules in an optical dipole trap. Starting from an ultracold gas mixture of K-40 and Rb-87 atoms, we…
Collisional stability of fermionic Feshbach molecules
J. J. Zirbel, K. -K. Ni, S. Ospelkaus +4
Using a Feshbach resonance, we create ultracold fermionic molecules starting from a Bose-Fermi atom gas mixture. The resulting mixture of atoms and weakly bound molecules provides…
Heteronuclear molecules in an optical lattice: Theory and experiment
Frank Deuretzbacher, Kim Plassmeier, Daniela Pfannkuche +5
We study properties of two different atoms at a single optical lattice site at a heteronuclear atomic Feshbach resonance. We calculate the energy spectrum, the efficiency of rf ass…
