In a recent paper (2019 Phys. Rev. A 99 , 053617), the total number of fermion pairs in a spin-balanced two-component Fermi gas of ^6 Li atoms was experimentally probed in the normal phase above the superfluid critical temperature, in order to invest

We investigate the evolution of quasi-static stray electric fields in a linear Paul trap over a period of several months. Depending on how these electric fields are initially induced we observe very different time scales for the field drifts. Photo-i

Atom and ion trapping provides new tools for ultracold chemistry. Using these techniques it is possible to measure the population distribution of the product states of three-body recombination in an ultracold atomic gas.

The emerging field of ultracold molecules with their rich internal structure is currently attracting a lot of interest. Various methods have been developed to produce ultracold molecules in pre-set quantum states. For future experiments it will be im

Throughout physics, stable composite objects are usually formed via attractive forces, which allow the constituents to lower their energy by binding together. Repulsive forces separate particles in free space. However, in a structured environment suc

We have performed a number of experiments with a Bose-Einstein condensate (BEC) in a one dimensional optical lattice. Making use of the small momentum spread of a BEC and standard atom optics techniques a high level of coherent control over an artifi

We report on a new sensitive method to minimize excess micromotion of an ion in a Paul trap. The ion is placed in an ultracold cloud of neutral Rb atoms in which ionic micromotion induces atomic losses and heating. Micromotion is minimized by applyin

Radio frequency spectra of a trapped unitary $^{6}\mathrm{Li}$ gas are reported and analyzed in terms of a theoretical approach that includes both final-state and trap effects. The different strength of the final-state interaction across the trap is
