Active stabilization of kilogauss magnetic fields to the ppm level for magnetoassociation on ultranarrow Feshbach resonances
Mateusz Borkowski, Lukas Reichsöllner, Premjith Thekkeppatt +4
Feshbach association of ultracold molecules using narrow resonances requires exquisite control of the applied magnetic field. Here we present a magnetic field control system to del…
Observation of Feshbach resonances between alkali and closed-shell atoms
Vincent Barbé, Alessio Ciamei, Benjamin Pasquiou +4
Magnetic Feshbach resonances are an invaluable tool for controlling ultracold atoms and molecules. They can be used to tune atomic interactions and have been used extensively to ex…
Quantum Engineering of a Low-Entropy Gas of Heteronuclear Bosonic Molecules in an Optical Lattice
Lukas Reichsöllner, Andreas Schindewolf, Tetsu Takekoshi +2
We demonstrate a generally applicable technique for mixing two-species quantum degenerate bosonic samples in the presence of an optical lattice, and we employ it to produce low-ent…
Ultracold dense samples of dipolar RbCs molecules in the rovibrational and hyperfine ground state
Tetsu Takekoshi, Lukas Reichsöllner, Andreas Schindewolf +6
We produce ultracold dense trapped samples of 87Rb133Cs molecules in their rovibrational ground state, with full nuclear hyperfine state control, by stimulated Raman adiabatic pass…
Molecular spectroscopy for ground-state transfer of ultracold RbCs molecules
Markus Debatin, Tetsu Takekoshi, Raffael Rameshan +7
We perform one- and two-photon high resolution spectroscopy on ultracold samples of RbCs Feshbach molecules with the aim to identify a suitable route for efficient ground-state tra…
Pinning quantum phase transition for a Luttinger liquid of strongly interacting bosons
Elmar Haller, Russell Hart, Manfred J. Mark +6
One of the most remarkable results of quantum mechanics is the fact that many-body quantum systems may exhibit phase transitions even at zero temperature. Quantum fluctuations, dee…
Confinement-Induced Resonances in Low-Dimensional Quantum Systems
Elmar Haller, Manfred J. Mark, Russell Hart +5
We report on the observation of confinement-induced resonances in strongly interacting quantum-gas systems with tunable interactions for one- and two-dimensional geometry. Atom-ato…
Inducing Transport in a Dissipation-Free Lattice with Super Bloch Oscillations
Elmar Haller, Russell Hart, Manfred J. Mark +3
Particles in a perfect lattice potential perform Bloch oscillations when subject to a constant force, leading to localization and preventing conductivity. For a weakly-interacting…
