We produce Bose-Einstein condensates of two different species, Rb 87 and K 41, in an
optical dipole trap in proximity of interspecies Feshbach resonances. We discover and …

Recent developments in the study of ultracold Rydberg gases demand an advanced level of
experimental sophistication, in which high atomic and optical densities must be combined …

We produce a heteronuclear quantum degenerate mixture of two bosonic species, Rb 87
and K 41, in a three-dimensional optical lattice. On raising the lattice barriers, we observe …

The bulk–boundary correspondence, a fundamental principle relating the topological
invariants of the bulk to the presence of edge states, is modified in periodically driven …

Laser cooling based on dark states, ie states decoupled from light, has proven to be effective
to increase the phase-space density of cold trapped atoms. Dark-states cooling requires …

We demonstrate a two-dimensional magneto-optical trap (2D MOT) as a beam source for
cold L 6 i atoms. The source is side loaded from an oven operated at temperatures in the …

We propose a Rydberg-atom-based single-photon detector for signal readout in dark matter
haloscope experiments between 40 μ eV and 200 μ eV (10 GHz and 50 GHz). At these …

Atom interferometers allow determining inertial effects to high accuracy. Quantum-projection
noise as well as systematic effects impose demands on large atomic flux as well as ultralow …

We report on the realization of a transversely loaded two-dimensional magneto-optical trap
serving as a source for cold strontium atoms. We analyze the dependence of the source's …

We describe the apparatus of a dark-line two-dimensional (2D) magneto-optical trap (MOT)
of 85 Rb cold atoms with high optical depth (OD). Different from the conventional …
