Meet us at the “Lange Nacht der Forschung” in Vienna

On the 13.th of April the “Lange Nacht der Forschung” (long night of research) will give everybody a great opportunity to get an idea about science and research made in Austria. Our contribution will be presented at the “Altes AKH” in Vienna where we are part of the team from the Vienna Doctoral Program of Complex Quantum Systems (COQUS). If you are around, please come by and discuss with us! The official program can be found here.

Spring meeting of the DPG in Erlangen

I just spend a very nice and inspriring week at the spring meeting of the German Physical Society in Erlangen, Germany. It’s great to come together with some many people, discuss in a very informal setting and make new connections you never thought of before.

Visit at Center for Free-Electron Laser Science in Hamburg

Last week I spend two very exciting days in the group of Jochen Küpper at the Center for Free-Electron Laser Science, which is at the Deutsches Elektronen Synchrotron in Hamburg, Germany. It’s amazing to take a look at research done in these large facilities with unique equipment like a free electron laser.

Matter-waves III

In this post we take a look at THE  prerequisite for matter-wave optics: how to make a particle behave like a wave.

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 molecules a number of these so-called conformers are present and that they easily interconvert at room temperature. In a new study we propose how such a sorting can be achieved with molecular interference. We show how internally cold beams populated with just a single structure can be prepared. These might open new vistas for structure-sensitive collision studies. More information can be found here soon.

All four structures show the same molecule, they only differ in the three-dimensional arrangement. With our method we can make sure that both first diffraction orders (±1) are populated only with the red conformer, while it is a mixture of a four conformers for all other diffraction orders.

Media’s response to our article

Our study on testing multi-path interference with massive particles has attracted a lot of attention since it was published two weeks ago. The latest is an article in Physics World by Edwin Cartlidge.
