Mott-Insulator-Aided Detection of Ultra-Narrow Feshbach Resonances
Manfred J. Mark, Florian Meinert, Katharina Lauber +1
We report on the detection of extremely narrow Feshbach resonances by employing a Mott-insulating state for cesium atoms in a three-dimensional optical lattice. The Mott insulator…
Observation of interspecies Feshbach resonances in an ultracold K-Cs mixture and refinement of interaction potentials
Michael Gröbner, Philipp Weinmann, Emil Kirilov +4
We observe interspecies Feshbach resonances due to s-wave bound states in ultracold K-Cs scattering for three different spin mixtures. The resonances are observed as…
Degenerate Raman sideband cooling of 39K
Michael Gröbner, Philipp Weinmann, Emil Kirilov +1
We report on the first realization of sub-Doppler laser cooling of 39K atoms using degenerate 3D Raman sideband cooling. We take advantage of the well-resolved excited hyperfine st…
A new quantum gas apparatus for ultracold mixtures of K and Cs and KCs ground-state molecules
Michael Gröbner, Philipp Weinmann, Florian Meinert +3
We present a new quantum gas apparatus for ultracold mixtures of K and Cs atoms and ultracold samples of KCs ground-state molecules. We demonstrate the apparatus' capabilities by p…
Model for the hyperfine structure of electronically-excited molecules
A. Orbán, R. Vexiau, O. Krieglsteiner +4
A model for determining the hyperfine structure of the excited electronic states of diatomic bialkali heteronuclear molecules is formulated from the atomic hyperfine interactions,…
Resonant atom-dimer collisions in cesium: Testing universality at positive scattering lengths
Alessandro Zenesini, Bo Huang, Martin Berninger +3
We study the collisional properties of an ultracold mixture of cesium atoms and dimers close to a Feshbach resonance near 550G in the regime of positive -wave scattering lengths…
