Our study on diffraction of helium and hydrogen atoms through freestanding graphene was just published in Science. And we even got featured in a perspective article by Bodil Holst from Bergen University. This is an incredible step for the whole … Continue reading →

New Scientist’s writer Alex Wilkens just published a very nice article, discussing our experiment on diffraction of atomic matter waves through graphene.

The summary of the second workshop on terrestrial very-long baseline atom interferometry has been published.

We made it! After years of planning, constructing, and testing we actually observed diffraction of atoms through single-layer graphene, a solid material. These are absolutely breath-taking results and we and the group of Toma Susi at the University of Vienna … Continue reading →

Just a short visit to Johannes Fiedler and the labs of Bodil Holst at the University of Bergen to plan new research activities.

Photochemistry and photophysics are rich fields of research as electronically excited molecules can undergo a large variety of deactivation processes. These include, but are not limited to, internal conversion, fragmentation, rearrangement of molecular bonds, fluorescence, and so on. In our … Continue reading →

We spent an enchanting week at the orthodox academy of Chania on Crete, discussing matter waves, enjoying the lovely weather, and swimming in the sea. Thanks go out to Wolf von Klitzing, his organizing team, and the scientific committee for … Continue reading →

Producing transmission grating using ion beam writing is known to deposit charges into the remaining material. This becomes an issue if you are diffracting polar molecules through such masks as the stray fields lead to random phase shifts, washing out … Continue reading →

Today, I was appointed Privatdozent at Ulm University after finishing my habilitation in experimental physics with a talk on “How to take a picture of a black hole”. In my thesis I present recent advances in beamsplitter techniques for massive … Continue reading →

We all know LIGO and its baffling sensitivity. When you come from the field of matter-wave physics, you cannot help wondering what such a very-long baseline experiments might bring for atom interferometry. This workshop summary discusses current ideas on this … Continue reading →
