A cavity optomechanical locking scheme based on the optical spring effect
Philipp Rohse, Jakob Butlewski, Felix Klein +6
We present a novel locking scheme for active length-stabilization and frequency detuning of a cavity optomechanical device based on the optical spring effect. The scheme can be use…
Dynamics of Ultracold Quantum Gases in the Dissipative Fermi-Hubbard Model
Koen Sponselee, Lukas Freystatzky, Benjamin Abeln +8
We employ metastable ultracold Yb atoms to study dynamics in the 1D dissipative Fermi-Hubbard model experimentally and theoretically, and observe a complete inhibition of t…
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 We report on twenty thus far unpublished Feshbach resonances and twent…
A millikelvin all-fiber cavity optomechanical apparatus for merging with ultra-cold atoms in a hybrid quantum system
Hai Zhong, Gotthold Fläschner, Alexander Schwarz +8
We describe the construction of an apparatus designed to realize a hybrid quantum system comprised of a cryogenically cooled mechanical oscillator and ultra-cold Rb atoms co…
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…
