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
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
Our paper on Bragg diffraction was selected as Editor’s Suggestion by Phys. Rev. Lett. and featured in a Synpsios in Physics.
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
Our manuscript on measuring laser beam profiles using a cut multi-mode fiber was published in Optics Express.
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
Our manuscript on preparing internally cold beams containing only a single molecular structure was published in Physical Review Letters.
In this post we take a look at THE prerequisite for matter-wave optics: how to make a particle behave like a wave.
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
