Prof. Dr. Jens Eisert heads the Quantum Computation and Simulation research group, which is jointly funded by Freie Universität Berlin and HZB. The theoretical physicist recently received an Advanced Grant from the European Research Council ERC for his research project "DebuQC". But Eisert is not only an award-winning scientist, he is also concerned about global warming. Last year, on the initiative of Ryan Sweke, he and his team published a proposal that deserves attention: scientific publications on theoretical physics or chemistry could include a simple table listing the greenhouse gases emitted during the research. This would raise awareness of the fact that research is not climate neutral.

The HZB researcher Rutger Schlatmann has been elected as the new Chair of the platform ETIP-PV, which brings together representatives of science, industry and politics from all over Europe. We interviewed him about the current boom – and about why the photovoltaics ship has not yet sailed for the EU.

At the end of October 2022, the management appointed Ana Sofia Anselmo and Silvia Zerbe as new diversity officers. Together they will address diversity at HZB and drive it forward with employees. Ana works in the Director’s Office and is responsible for International Affairs. Silvia is deputy press spokesperson at HZB and is dedicated to internal communication at the centre.

Tandem solar cells, which combine two different perovskite semiconductors, promise high efficiencies and can be produced with very little energy input. Such modules could even be bendable. Together with partners from industry and research, HZB expert Prof. Steve Albrecht is working to realise this vision. His team recently succeeded in producing an all-perovskite tandem solar cell with a certified efficiency of 27.2 %. A conversation about the opportunities and challenges of the perovskite-perovskite technology.

In the research consortium CARE-O-SENE, scientists are looking for more efficient ways to produce synthetic kerosene for use in aviation. We interviewed Tobias Sontheimer of HZB and Dirk Schär of the participating company Sasol about what has to be done, what obstacles there are, and how aviation can be decarbonised.

Collaborative Research projects as “Sonderforschungsbereiche” funded by Deutsche Forschungsgemeinschaft enable universities to build up their own research capacities. In the Transregio Sonderforschungsbereich 227 Ultrafast Spin Dynamic, the Freie Universität Berlin and the University in Halle-Wittenberg have also included HZB as a partner. The slicing facility of BESSY II plays a central role in this collaboration. With excellent results from the first phase, the Transregio-SFB 227 has completed its first interim review and is now preparing for the challenges ahead. A conversation with the two HZB physicists Niko Pontius and Christian Schüßler-Langeheine about the importance of such funding programmes for the research field.

Turning a scientific question into a product is the requirement that the winners of the HZB Technology Transfer Prize should fulfil. The team led by Tobias Henschel, Bernd Stannowski and Sebastian Neubert won more than just a prize.

Prof. Dr. Udo Heinemann works at the Max Delbrück Center for Molecular Medicine, where he has been researching in structural biology for 40 years. From 2008 to 2012, he was a member of the Advisory Board for the Protein Data Bank in Europe. In an interview, he speaks of the value added by the Protein Data Bank for research today, and why it is important that there are specialised beamlines for structural biology analysis in Berlin.

Bereits im dritten Jahr in Folge darf sich das HZB über einen außergewöhnlichen Erfolg bei der Feinwerkmechaniker-Ausbildung freuen. Shayne Fraiss beendete seine Ausbildung als Bester seines Jahrgangs in Berlin. Wir haben ihn und seine Ausbilder gefragt, was das Geheimrezept für diesen Erfolg ist.

Freie Universität Berlin and Helmholtz-Zentrum Berlin (HZB) are now strengthening their cooperation in the field of quantum computing with a new research group. Quantum materials exhibit very interesting properties, which researchers want to use to make data processing significantly faster and more efficient than is currently possible. They can study these materials excellently at synchrotron radiation sources such as BESSY II. It has proven especially promising to predict the material properties in quantum simulations before running the experiments. Taking this approach allows such experiments to be conducted more targetedly.
