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…
Do mixtures of bosonic and fermionic atoms adiabatically heat up in optical lattices?
M. Cramer, S. Ospelkaus, C. Ospelkaus +3
Mixtures of bosonic and fermionic atoms in optical lattices provide a promising arena to study strongly correlated systems. In experiments realizing such mixtures in the quantum de…
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…
