Our group performs experiments on quantum physics of ultracold atoms, high resolution laser spectroscopy of single trapped ions and antimatter spectroscopy. We are located at the LMU University of Munich and at the Max-Planck Institute of Quantum Optics in Garching.

Watching the heart beat of molecules
A team of scientists around Prof. T.W.Hänsch and Dr. N.Picqué at the MPQ, in a collaboration with the LMU Munich and the Institut des Sciences Moléculaires d’Orsay now report on a new method of rapidly identifying different molecular species under a microscope. ...more
On wings of light

Dr. Nathalie Picqué receives the Coblentz Award
The Coblentz Society has elected Dr. Nathalie Picqué as this year’s recipient of the Coblentz Award. Dr. Picqué is currently on long-term leave at the Max-Planck-Institute of Quantum Optics and the Ludwig-Maximilians-Universität Munich ...
Proton size puzzle reinforced!
The initial results puzzled the world three years ago: the size of the proton (to be precise, its charge radius), measured in exotic hydrogen, in which the electron orbiting the nucleus is replaced by a negatively charged muon, yielded a value significantly smaller than the one from previous investigations of regular hydrogen or electron-proton-scattering. ...
Frequency combs for sniffing molecules
Most molecules, including those of importance in medical diagnostics or pollution monitoring, have characteristic “fingerprints” in the mid-infrared spectral region. However, state-of-the-art mid-infrared frequency comb techniques require systems that are often costly and limited in their applications.
