Investigation of Feshbach Resonances in ultra-cold 40 K spin mixtures
Jasper S. Krauser, Jannes Heinze, S. Götze +7
Magnetically-tunable Feshbach resonances are an indispensable tool for experiments with atomic quantum gases. We report on twenty thus far unpublished Feshbach resonances and twent…
Engineering spin waves in a high-spin ultracold Fermi gas
Jannes Heinze, Jasper Simon Krauser, Nick Fläschner +5
We report on the detailed study of multi-component spin-waves in an s=3/2 Fermi gas where the high spin leads to novel tensorial degrees of freedom compared to s = 1/2 systems. The…
Intrinsic Photoconductivity of Ultracold Fermions in Optical Lattices
J. Heinze, J. S. Krauser, N. Fläschner +6
We report on the experimental observation of an analog to a persistent alternating photocurrent in an ultracold gas of fermionic atoms in an optical lattice. The dynamics is induce…
Multi-band spectroscopy of ultracold fermions: Observation of reduced tunneling in attractive Bose-Fermi mixtures
J. Heinze, S. Götze, J. S. Krauser +5
We perform a detailed experimental study of the band excitations and tunneling properties of ultracold fermions in optical lattices. Employing a novel multi-band spectroscopy for f…
