Halle’s Physicists on a Pathway to Success

26.04.2018 von Tom Leonhardt in Featured, Research
Knowledge transfer is only successful when it is coupled with excellent basic research. The staff at the Institute of Physics are doing just that. The institute is not only home to three collaborative research centres (CRC) of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) and one Alexander von Humboldt professorship. Its researchers have excellent international ties and have regularly attracted notice through articles published in renowned journals.

Gut gelaunt sitzen Prof. Dr. Ingrid Mertig, Prof. Dr. Thomas Thurn-Albrecht und Prof. Dr. Georg Woltersdorf in einem Büro im Institut für Physik. Die drei haben sich viel zu erzählen. Über gemeinsame Projekte, anstehende und zurückliegende Dienstreisen sowie vielversprechende Studierende in ihren Vorlesungen. Der regelmäßige Austausch ist bei den Physikern Alltag. „Das Markenzeichen unseres Instituts ist, dass wir viel und vor allem gut zusammenarbeiten“, fasst Ingrid Mertig zusammen. Ihre beiden Kollegen nicken zustimmend.

Die drei Wissenschaftler eint, dass sie alle Sprecher oder stellvertretende Sprecher je eines von der Deutschen Forschungsgemeinschaft geförderten Sonderforschungsbereichs sind: Mertig leitet den seit 2008 bestehenden SFB 762 „Funktionalität oxidischer Grenzflächen“. Thomas Thurn-Albrecht ist Sprecher des gemeinsam mit der Universität Leipzig 2011 etablierten Transregio-SFB 102 „Polymere unter Zwangsbedingungen“. Georg Woltersdorf gelang es im vergangenen Jahr, gemeinsam mit der Freien Universität Berlin den neuen Transregio-SFB 227 „Ultraschnelle Spin­dynamik“ einzuwerben.

Alle drei Initiativen sind eingebettet in den naturwissenschaftlichen Forschungsschwerpunkt „Materialwissenschaften – Nanostrukturierte Materialien“ an der Universität, der sich mit der Entwicklung neuartiger Materialien und innovativer Messmethoden befasst.  Hier ist auch das Zentrum für Innovationskompetenz „SiLi-nano“ angesiedelt, das vom Bundesministerium für Bildung und Forschung finanziert wird.

A Strong Network

There is a long history of success at the Physics Institute. “Oxide interfaces, polymer physics and photovoltaics have been the core research areas of our institute for many years,” explains Mertig. She points to the non-university partners on site that have strong research capabilities: the Max Planck Institute for Microstructure Physics (MPI), the Fraunhofer Institute for Microstructure of Materials and Systems IMWS and the Fraunhofer Centre for Silicon Photovoltaics. “A lot of what we have achieved today would not be possible without the cooperation with our non-university partners.”

When Mertig was appointed professor of quantum theory of the solid state in 2001, many professors at her institute in Halle had just retired or were close to retirement. “That was a good opportunity to further raise the institute’s profile,” the physicist recalls. Together with colleagues, she developed a new research profile for the institute. Research focused on solid state materials and polymers, while other activities were put on hold. The vacant professorships were to be developed accordingly and strategically filled by promising researchers.  

“Our guiding principle is the establishment of core groups in Halle in order to attract further projects,” explains Thomas Thurn-Albrecht, a professor of polymer physics in Halle since 2003. This network is a strong asset of the physics institute that, with 14 professors, is otherwise rather small. Often various groups share research equipment. This strengthens scientific exchange and fosters collaboration, which, in an ideal case, results in the successful funding of projects.

Georg Woltersdorf, who is a prime example of the strategic appointment process, has been nurturing the latest success. After the assessment of CRC 762 it became apparent that the research profile in Halle could profit from the addition of ultrafast dynamics – Woltersdorf’s speciality. In 2013 Woltersdorf was appointed professor of optics in Halle. Just four years later, the researcher was able to obtain funding for a new CRC in collaboration with Freie Universität Berlin. The subject: ultrafast spin dynamics.

Physics in Halle Draws International Attention

Halle’s Institute of Physics has made an international name for itself – both as a location for international conferences and as a host institute of highly regarded guest researchers. In partnership with MPI, its physicists were able to attract to Halle Professor Stuart Parkin, the inventor of modern hard drive technology, through an Alexander von Humboldt professorship – Germany’s most highly endowed international research award. French Nobel Laureate in physics, Professor Albert Fert has also been a guest of the institute since 2014. And just a few weeks ago, Dr Manuel Bibes from the renowned Centre national de la recherche scientifique (CNRS) Thales received the Friedrich Wilhelm Bessel Research Award from the Alexander von Humboldt Foundation, which allows him to work for several months in Halle.

Despite their many successes the three professors remain unassuming. “We are always en route,” says Thomas Thurn-Albrecht, referring to two more topics that are near and dear to him: teaching and junior scientists. “It’s a pleasure to be able to share creative moments during my work with highly talented young people,” adds Mertig. The institute is well-placed in terms of PhD positions thanks to the CRC funding. One sticking point, however, is the lack of permanent positions at the institute and at the university as a whole once students finish their PhD studies. “It hurts to lose excellent colleagues because we are unable to offer them reliable prospects,” says Woltersdorf. Here the three researchers see an area for improvement in the future.

They will continue to work on the profile of their institute in the future even though it takes time and effort. Georg Woltersdorf’s face lights up when he explains how the small physics institute in Halle is able to selectively contribute to top international research. “This kind of success is fun!”

“Flexibility is our advantage”

The Weinberg Campus is a high-tech location. In the last 25 years around one billion euros has been invested in a site that is also the heart of the university’s scientific campus. The density of research institutes is high on the nearly 134-hectare site. This is accompanied by numerous successful companies that have often emerged from start-ups. Important drivers of the process are technology and founders’ centres. The first one opened in 1993 and the technology park was born. Professor Reinhard Neubert - a scientist, Prorector and entrepreneur - is one of the pioneers of this development. He talks with Ines Godazgar in an interview. Read more

Cutting-Edge Research Where Vineyards Once Grew

The area between the Heide district in Halle and the river Saale was used in the past for very different things. The land-use demarcation “vineyard” (Weinberg in German) was based on the fact that vineyards had been officially documented multiple times on this land since the 13th century. The fruit played such an important role in Mediaeval wine culture that in 1750 the chronicler Dreyhaupt compared the good wine to that of the Rhine Valley. Read more
