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…
Magnetically tuned spin dynamics resonance
J. Kronjäger, C. Becker, P. Navez +2
We present the experimental observation of a magnetically tuned resonance phenomenon resulting from spin mixing dynamics of ultracold atomic gases. In particular we study the magne…
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…
Evolution from a Bose-Einstein condensate to a Tonks-Girardeau gas: An exact diagonalization study
Frank Deuretzbacher, Kai Bongs, Klaus Sengstock +1
We study ground state properties of spinless, quasi one-dimensional bosons which are confined in a harmonic trap and interact via repulsive delta-potentials. We use the exact diago…
