Single-, double-, and triple-slit diffraction of molecular matter-waves
Christian Brand, Stephan Troyer, Christian Knobloch +2
Even 100 years after its introduction by Louis de Broglie, the wave-nature of matter is often regarded as a mind-boggling phenomenon. To give an intuitive introduction to this fiel…
Bragg diffraction of large organic molecules
Christian Brand, Filip Kiałka, Stephan Troyer +5
We demonstrate Bragg diffraction of the antibiotic ciprofloxacin and the dye molecule phthalocyanine at a thick optical grating. The observed patterns show a single dominant diffra…
A fiber-based beam profiler for high-power laser beams in confined spaces and ultra-high vacuum
Christian Brand, Ksenija Simonović, Filip Kiałka +3
Laser beam profilometry is an important scientific task with well-established solutions for beams propagating in air. It has, however, remained an open challenge to measure beam pr…
Conformer-selection by matter-wave interference
Christian Brand, Benjamin A. Stickler, Christian Knobloch +3
We establish that matter-wave interference at near-resonant ultraviolet optical gratings can be used to spatially separate individual conformers of complex molecules. Our calculati…
Matter-wave physics with nanoparticles and biomolecules
Christian Brand, Sandra Eibenberger, Ugur Sezer +1
These lecture notes emerged from a contribution to the "Les Houches Summer School, Session CVII - Current Trends in Atomic Physics, July 2016". It is meant to serve students as a g…
An atomically thin matter-wave beamsplitter
Christian Brand, Michele Sclafani, Christian Knobloch +9
Matter-wave interferometry has become an essential tool in studies on the foundations of quantum physics and for precision measurements. Mechanical gratings have played an importan…
