Open positions in VDS Physics


The Vienna Doctoral School in Physics offers doctoral training across all key research areas of the Faculty of Physics at the University of Vienna. You can apply to the program all year around. In order to start your PhD at the University of Vienna, you need to find a supervisor who can offer you a position.

Currently, we offer the following positions

Quantum Nanophysics
(Univ.-Prof. Dr. Markus Arndt)

Optical Charge Control & Quantum Detection of Proteins
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.

Cooling of Nanoparticles towards 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. Over recent years good progress has been made in preparing and cooling nanoparticles in 1D. This has now to be extended to more degrees of freedom, lower temperatures and to particle sources that can provide nanoparticles on demand or at least in a heralded way with a high repetition rate. The PhD position is dedicated to developing particle sources and the cooling techniques that shall eventually become ready as a reliable source for matter-wave interference experiments in a rugged and repeatable design.

Metal Cluster Beams for LUMI 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 PhD student working on this project should be interested in and ideally already experienced in matter-wave, cluster, laser and vacuum physics, as well as general lab technologies including data acquisition and processing.

Nonlinear Optics and Photosensitive Materials
(ao. Univ.-Prof. Dr. Martin Fally)

Polymer based photonic materials for Neutron optics
Joint PhD research position at Institut Laue Langevin and University of Vienna
Great opportunity of Vienna-supervised PhD project at one of Europe’s most vibrant hubs for science students. Nestled in the French Alps, the Institut-Laue Langevin in Grenoble is Europe’s flagship centre for neutron science and part of Grenoble’s EPN science campus with dynamic activities in molecular biology, condensed matter physics, micro electronics and nanotechnology.
The project involves study of nanomaterials, design of prototypes of diffractive optics for neutron science and tests of novel methods the former might render possible. Your work will push forward science with long-wavelength neutrons and extend its possibilities beyond the previously unknown.
While knowledge of the French language is not a prerequisite for motivated candidates, interest in optics, good communication skills and the willingness to move to Grenoble are necessary.

Quantum Imaging and Biophysics
(Ass. Prof. Dr. Thomas Juffmann) 

Cavity enhanced microscopy for live cell imaging
Phase microscopy has applications from biology to diagnostics. In your project you will employ cavities and wave-front shaping techniques to push the sensitivity of phase microscopy. In an interdisciplinary environment at the interface of physics and biology you will design and use your tools for live cell microscopy, as well as for the detection of single proteins.

Electron optics made from light
Electron microscopy has revolutionized our understanding of structural biology. While the technology is considered mature, the interaction of electrons with intense lasers recently opened new possibilities for electron optics. In your project you will use femtosecond laser pulses to shape the wave-front of an electron beam via shaped ponderomotive potentials. This will allow for a new class of electron optics of unprecedented versatility.

These two experimental PhD positions are available within the framework of the ERC Starting Grant MicroMOUPE.

Low Dimensional Quantum Solids
(Univ. Prof. Dr. Thomas Pichler)

1D, 2D and 3D Metal-organic frameworks (MOFs)
MOFs represent a new class of compounds that consist of metal nodes and organic ligands to form various nanostructures. Our project, in cooperation with TU Wien and J. Heyrovsky Institute of Physical Chemistry in Prague, aims to study quantum confinement effects in MOFs for optoelectronic and spintronic applications.
