The audience voted on 22 September 2021 for Barbara's presentation entitled "Quantendisco im Supermagnet". She won the Macke Award for her Master Thesis "Magnetophotoluminescence study of excitons confined in GaAs quantum dots".
The other nominees were Mario Graml (Dept. MINT Didaktik) and Sebastian Paischer (Abteilung Vielteilchensysteme).

Based on a simple physical principle that uses water to generate electrostatic charges, the charged water droplets dance and move fluidly around copper rods, reacting to nearby objects. The charged water makes metal flowers bloom and interact, generating long flashes of light at times.
The underlying physical phenomenon for this exhibition is referred to as ‘Influence’ and identical charge-carriers repel each other while opposite ones attract each other. The energy from the falling water droplets is converted into electrostatic charges. There is no need for any electronics and or hidden energy sources; just electricity for the water pump.

At the virtual festival "29. Internationale Wirtschaftsfilmtage 2020", opens an external URL in a new window, the movie "Cats, Rats and Lovebirds", written by Moritz Brehm and Martyna Grydlik, won the Silver Cup of the "Grand Prix Victoria" in the category "Technology, Research and Development" in June 2020.
This article, opens an external URL in a new window gives an introduction on Professor Rastellis research on quantum computing in Linz.
This booklet, written by Professor Rastelli and graphically designed by his wife Nathalie, is designed for school pupils as well as interested adults, and is trying to explain in easy words the "strange world of artificial atoms". Its aim is to give a playful first insight into the exciting field of quantum physics, including many easy experiments and explanations referring to the everyday world around us.
It is actually based on the EC-project HANAS (Hybrid Artificial and Natural Atomic Systems, 2013-2016).

The project Hybrid Artificial and Natural Atomic Systems (HANAS, 2013-2016), funded by the European Union within the FP7 program, brings together complementary expertise from research groups at the Technical University Delft, Johannes Kepler University Linz, the Institute of Solid State and Materials Research Dresden, CEA Grenoble, and Max-Planck-Intitute for Quantum Optics Munich. We have poduced a video, describing the research goals of the project.
In 2015, a new electron-beam machine had been purchased and installed in the cleanroom of the institute. We made a Video on YouTube, opens an external URL in a new window about it.
