Markus Arndt

PhD opportunity in quantum nanophysics at the University of Vienna, Austria. The Quantum Nanophysics team around Prof. Markus Arndt is recruiting a University assistant predoctoral / PhD candidate for a 4-year research position in experimental physics. The project is linked to V-QUTE and focuses on pushing the limits of matter-wave interferometry with nanoparticles, including very cold particle sources, quantum coherent beam splitters, advanced detectors, ultraviolet laser systems, quantum sensing, mass spectrometry, and biomolecular chemistry. The group works at the interface of quantum and classical physics and quantum/bio-molecular science, with strong expertise in molecular beams, ultra-high-vacuum systems, nanoparticle cooling, cluster science, optics, and laser technology. Applicants should have a completed Master’s degree or Diploma in physics (or equivalent qualification enabling PhD enrollment at the University of Vienna). The post asks for strong experimental skills, hands-on experience in at least two relevant technical areas, and excellent English. A structured four-year Bachelor’s degree may also be considered if it qualifies for PhD admission. This is a paid position with a gross salary of EUR 3,776.10 per month on a full-time basis (14x per year), with possible salary progression based on prior experience. The contract runs for 4 years, initially limited to 1.5 years and then automatically extended if not terminated early. How to apply: Submit one English PDF containing your CV, research-interest statement, one-page motivation letter referencing a recent publication from quantumnano.at , and a summary of achievements. Apply through the University of Vienna jobs portal before 2026-08-24 .

The University of Vienna is advertising a University assistant predoctoral / PhD candidate position in the Faculty of Physics within the Quantum Nanophysics team led by Prof. Markus Arndt . The project is linked to Q4-BIO , a new research direction at the interface of quantum physics , biomolecular chemistry , and experimental nanophysics. The research focuses on universal matter-wave interferometry at high mass and high complexity, including organic molecules, metal clusters, dielectric nanoparticles, molecular beams, levitated optomechanics, quantum sensing, mass spectrometry, and biomolecular chemistry. The team also works within the Austrian Cluster of Excellence (qAustria), the Vienna Doctoral School in Physics (VDSP), and the Vienna Center for Quantum Science and Technology (VCQ). Eligibility highlights: applicants must have a completed Master's degree or Diploma in physics, or an equivalent qualification allowing PhD enrollment at the University of Vienna. Strong experimental background is essential, especially hands-on experience in at least two of the following: molecular beam sources, cryogenic ultra-high-vacuum systems, superconducting nanowire detectors, advanced optics, laser systems and frequency conversion, mass spectrometry, or matter-wave research. Excellent English is required, and candidates should be able to document laboratory design, construction, and troubleshooting skills. Funding and terms: this is a paid university assistant position with a 4-year employment duration. The salary starts at EUR 3,776.10 gross per month (40h/week, 14 payments/year), with possible increases for recognized experience. The contract is initially limited to 1.5 years and may be extended to the full 4 years. Application: submit one English PDF containing a scientific CV, a short statement of research interests, a one-page motivation letter referencing a relevant recent publication from quantumnano.at, and a summary of academic and research achievements. Deadline: 2026-08-11 .
