Master Thesis Opportunities

Optomechanics for Matter-Wave Interferometry

Our group has been a leader in high-mass matter-wave experiments for many years and is now working towards pushing the mass limit further using dielectric nanoparticles and biological nanomatter. The goal of this thesis is extend cooling nanoparticles on demand or at least in a heralded way at high repetition rate. The master thesis is dedicated to developing particle sources and cooling techniques in preparation for advanced matter-wave interference experiments.  

Optical Charge Control & Quantum Detection of Polypeptides

In 2019, the European Commission has granted the new FET Open project Superconducting Mass Spectrometry and Molecule Analysis (SuperMaMa). The SuperMaMa consortium is a highly interdisciplinary team combining technology-intense SMEs in mass spectrometry (MSVISION) and superconductor detector technology (SQ) as well as three university research labs specialized in integrated electronic engineering (EPFL), synthetic and biomolecular chemistry (UNIBAS), as well as molecular beam physics, quantum optics and mass spectrometry techniques (UNIVIE). The project is coordinated by Markus Arndt at the University of Vienna. We aim at developing at quantum detectors for biomolecular mass spectrometry as well as bond-specific photo-cleavage as a technique for optical charge control of proteins in the gas phase. These tools are important for a growing industry in molecule mass and optical spectroscopy and they will lay the ground for new quantum optics experiments with proteins.

Cold Metal Clusters for Matter-wave Interferometry

Recently, we have been able to demonstrate matter-wave coherence for particles in the mass range > 25 kDa, for the first time. In an effort to extend this feat to higher masses we are now setting up a new beam line for cold metal clusters, aiming eventually at interferometry in the mass range >300 kDa. This requires the combination of various tools of mass spectrometry, ion guiding, trapping, filtering and cooling, together with new optical control techniques.
The master student working on this project should be interested in matter-waves, cold metal clusters , laser and vacuum physics, data acquisition and processing.
