An electrostatic bottle for cold molecules

Max Planck Institute of Quantum Optics Junglen, Tobias; Pinkse, Pepijn; Rieger, Thomas; Rempe, Gerhard
Abstract The production and investigation of cold molecules is a young and fascinating field of research. In our research group, electric fields were used to filter slow polar molecules out of a thermal gas. These molecules could be trapped in an electric cage for 300 ms where their temperature amounts to 300 mK. more

Counting faster than Light

Max Planck Institute of Quantum Optics Gohle, Christoph; Herrmann, Maximilian; Udem, Thomas; Hänsch, Theodor W.
The frequency comb technology that was awarded the Noble Prize of Physics enables frequency measurements of highest accuracy and the development of high-precision “optical clocks”. New applications e.g. in geology as well as new discoveries concerning fundamental physical theories can be envisioned. more
