Claas ABERT - Machine Learning Methods for Inverse Micromagnetic Modelling
Numerical simulations of magnetic nanosystems have been an important driver for the development of a multitude of novel magnetic and spintronics devices. Micromagnetic simulations are an established field and various simulation tools for this model have been developed during the past years.
Within this project, we want to adapt our latest simulation tool magnum.np (https://gitlab.com/magnum.np/magnum.np) to handle inverse modelling problems using the automatic differential capabilities of novel machine learning frameworks such as PyTorch.

Markus ASPELMEYER & Nikolai KIESEL - Quantum optomechanics with levitated solids
The scope of this internship is to receive practical training on the experimental and theoretical methods to realize quantum optical control over nano- and microscale solid-state systems. Particular focus is given to the question how to increase coherent delocalization of a massive quantum object. The internship will involve hands-on practical experience and direct participation as team member in one of our experiments that address these topics.

Andrii CHUMAK- Magnetic spheres for magnonic quantum technology
The field of magnonics predominantly involves operating with coherent spin waves and their quanta -magnons- at room temperature to process information. To fully leverage the computational capabilities of spin waves, it is imperative to exploit the quantum nature of magnons and delve into the underlying physics of entangled magnonic or hybrid quantum states. This project situates itself within the framework of quantum magnonics, aiming to manipulate entangled single magnons at millikelvin temperatures. The primary objective of the project will be to characterize magnetic spheres of yttrium iron garnet (YIG) and to measure the correlation between magnon lifetime and temperature.
The project is experimental.
It goes in the frames of “quantum magnonics project”: https://nanomag.univie.ac.at/research/quantum-magnonics/

Borivoje DAKIC - Characterization theory in large-scale quantum systems
The Operational Quantum Information group ( https://dakic.univie.ac.at/) conducts research in quantum information theory and quantum foundations. The internship (up to 3 months) offers an opportunity to work on various mini-research projects and computational tasks related to verification and characterization theory in large-scale quantum systems (see: https://dakic.univie.ac.at/research/diagnostics-for-large-scale-quantum-systems/). A background in general quantum information theory, linear algebra, and probability theory is required to qualify for the internship.

Thomas JUFFMANN - Colibri: Combining lifetime measurements with brilliant imaging
Fluorescence lifetime microscopy yields information about the local environment of a fluorophore (pH, binding partners, ion concentration...), which is crucial for analyzing the metabolic state of cells and tissue. We have built a detector that can measure fluorescence lifetimes orders of magnitude faster than previously possible. This enables combining lifetime measurements with other advanced microscopy techniques such as light-sheet or super-resolution microscopy.
You will work in close collaboration with biologists in order to optimize our lifetime detector for specific life-science applications.
We are looking for motivated master's students with a passion for science. The work requires a background in physics. Programming and mathematical skills are highly appreciated.
You will learn how to:
- Build a microscope
- Control and automate measurements
- Analyze Data
- Collaborate in an inter-disciplinary environment
- See what no one has seen before

Thomas JUFFMANN - Label-free super-resolution microscopy
Optical microscopy is typically limited to a spatial resolution given by the wavelength of light. Super-resolution microscopy overcomes this limit, building on the level structure of fluorescent labels. We aim to demonstrate label-free super-resolution microscopy techniques, e.g. by harnessing optical near-fields as in optical near-field electron microscopy. You will be working in a team of physicists to enable nanometric resolution in applications ranging from electrochemistry to biophysics.

Jani KOTAKOSKI - 2D materials at the atomic resolution
Several projects are offered for excellent students who want to explore the family of 2D materials at atomic resolution. 2D materials were discovered nearly two decades ago, when graphene was the first time exfoliated from a stack of graphite, and its extraordinary electronic and mechanical properties were demonstrated. Since then, hundreds of other materials that exist in 2D form have been demonstrated. One of the main research topics of the Kotakoski research group is developing methods for controlling the atomic structure of 2D materials by introducing and manipulating atomic-scale defects, and their study using atomistic simulations and (scanning) transmission electron microscopy and electron energy loss spectroscopy. The projects can be adjusted based on the interests and experience of the candidate.
