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…
Ultracold heteronuclear molecules in a 3D optical lattice
C. Ospelkaus, S. Ospelkaus, L. Humbert +3
We report on the creation of ultracold heteronuclear molecules assembled from fermionic 40K and bosonic 87Rb atoms in a 3D optical lattice. Molecules are produced at a heteronuclea…
Tuning of heteronuclear interactions in a quantum-degenerate Fermi-Bose mixture
S. Ospelkaus, C. Ospelkaus, L. Humbert +2
We demonstrate tuning of interactions between fermionic 40K and bosonic 87Rb atoms by Feshbach resonances and access the complete phase diagram of the harmonically trapped mixture…
Localization of bosonic atoms by fermionic impurities in a 3d optical lattice
S. Ospelkaus, C. Ospelkaus, O. Wille +4
We observe a localized phase of ultracold bosonic quantum gases in a 3-dimensional optical lattice induced by a small contribution of fermionic atoms acting as impurities in a Ferm…
Interaction-driven Dynamics of 40K / 87Rb Fermi-Bose Gas Mixtures in the Large Particle Number Limit
C. Ospelkaus, S. Ospelkaus, K. Sengstock +1
We have studied effects of interspecies attraction in a Fermi-Bose mixture over a large regime of particle numbers in the 40K / 87Rb system. We report on the observation of a mean…
Dynamics and thermodynamics in spinor quantum gases
H. Schmaljohann, M. Erhard, J. Kronjäger +2
We discuss magnetism in spinor quantum gases theoretically and experimentally with emphasis on temporal dynamics of the spinor order parameter in the presence of an external magnet…
