Few-slit diffraction with molecules
In matter-wave diffraction, we use the laws of optics to describe the behaviour of delocalized matter, be it electrons, atoms, or molecules. This entails a number of questions, such as: How do I generate a matter wave in the first … Continue reading

The morphology of doubly-clamped graphene nanoribbons
When you pull at the two ends of a scarf, folds start to build up in the fabric. When you do the same for a ribbon made of single-layer graphene, you get folds, scrolls or just a flat membrane. How … Continue reading
Paper on Bragg diffraction selected as Editor’s Suggestion
Our paper on Bragg diffraction was selected as Editor’s Suggestion by Phys. Rev. Lett. and featured in a Synpsios in Physics.
Bragg diffraction of large organic molecules
Bragg diffraction is one of the main techniques used to split and recombine atomic matter-waves. In our latest publication we transfer this technique to complex and internally hot molecules. Why this is a big step towards more efficient beam … Continue reading
Publication in Optics Express
Our manuscript on measuring laser beam profiles using a cut multi-mode fiber was published in Optics Express.
Finding the ultimate grating for atomic matter-waves
What happens when you accelerate hydrogen atoms to a breathtaking velocity of 120’000 m/s and shoot them onto the thinnest membrane there is? You get an absolutely fascinating diffraction pattern! In our latest publication we theoretically describe what to expect … Continue reading
Publication in Physical Review Letters

Spatial separation of molecular conformers with interference
The task to sort molecules can be quite challenging if they are very similar. This is even more the case if you want to sort a single molecular species according to its three-dimensional structure. The problem is that for most … Continue reading
Testing Born’s rule with molecules
Born’s rule is one of the cornerstones of quantum physics. Needless to say that a potential violation of this rule might point to something very interesting happening. In a brand new publication we report about the first explicit test of … Continue reading
