Reinforcement Learning in Ultracold Atom Experiments
Malte Reinschmidt, József Fortágh, Andreas Günther +1
Cold atom traps are at the heart of many quantum applications in science and technology. The preparation and control of atomic clouds involves complex optimization processes, that…
Outcoupling from a Bose-Einstein condensate in the strong-field limit
Caroline Arnold, Carola Beck, Peter Federsel +4
Atoms can be extracted from a trapped Bose-Einstein condensate (BEC) by driving spin-flips to untrapped states. The coherence properties of the BEC are transfered to the released a…
Absolute frequency measurement of rubidium 5S-6P transitions
Conny Glaser, Florian Karlewski, Jens Grimmel +4
We report on measurements on the 5S-6P rubidium transition frequencies for rubidium isotopes with an absolute uncertainty of better than \SI{450}{kHz} for the 5S 6P$_…
Structural, magnetic, electric, dielectric, and thermodynamic properties of multiferroic GeV4S8
S. Widmann, A. Günther, E. Ruff +4
The lacunar spinel GeV4S8 undergoes orbital and ferroelectric ordering at the Jahn-Teller transition around 30 K and exhibits antiferromagnetic order below about 14 K. In addition…
Intermediate-valence behavior of the transition-metal oxide CaCuRuO
A. Krimmel, A. Günther, W. Kraetschmer +7
The transition--metal oxide CaCuRuO with perovskite--type structure shows characteristic properties of an intermediate--valence system. The temperature--dependent su…
Optical Spectroscopy of Ultracold Atoms on an Atom Chip
A. Günther, H. Bender, A. Stibor +2
We experimentally demonstrate optical spectroscopy of magnetically trapped atoms on an atom chip. High resolution optical spectra of individual trapped clouds are recorded within a…
