In January 2024 MolCal, a MSCA Doctoral Network starts whose overarching scientific goal is the preparation of new molecular assemblies with outstanding potential as caloric materials for refrigeration and heat pump applications at near-ambient and very-low temperature, and their exploitation in prototype devices. MolCal will offer PhD candidates the unique opportunity to boost their personal and career prospects by joining a cutting-edge interdisciplinary research and training programme. Activities will encompass chemistry, materials science, physics, and device fabrication.
Participating partners: CSIC, The University of Edinburgh, University of Crete, Bielefeld University, University of Seville, University Paris-Saclay, CNR, SunAmp, University of Zaragoza, Eindhoven University of Technology, Quantum Design North America, Lake Shore Cryotronics, BSH Spain.
Contact in Bielefeld: Prof. Dr. Jürgen Schnack
The question of how a system responds to an external perturbation is ubiquitous in physics. In our publication specified below, we report on the remarkable discovery that a large class of many-body systems turns out to be surprisingly resilient against such perturbations as long as the unperturbed system finds itself close to thermal equilibrium.
The first author, Lennart Dabelow, got his PhD from Bielefeld University and is presently a Lecturer at Queen Mary University of London. The second author, Peter Reimann, has been at Bielefeld University's Faculty of Physics since 2002.

The nationwide Particle World network brings together research institutes, pupils and learning centres to attract young people to mathematics, computer science, natural sciences and technology - the STEM subjects. Together, young people and teachers are to be taught about particle physics in an exciting and understandable way. Bielefeld University is now part of the nationwide project. Its first contribution is a public presentation followed by a workshop on Saturday, 11 November. Professor Dr Sören Schlichting from Bielefeld University will then present the work of the LHC (Large Hadron Collider) particle accelerator at the CERN research centre in Geneva.

For the first time, Bielefeld University has simultaneously acquired four Consolidator Grants from the European Research Council (ERC). The prestigious funding goes to the health scientists Professor Dr Anna Oksuzyan and Professor MD Kayvan Bozorgmehr, the physicist Professor Dr Gergely Endrödi and the social anthropologist Dr Megha Amrith. The grants will be sponsored with a total of more than 8 million euros, of which 7.3 million euros will go to Bielefeld University. The four research projects are scheduled to start in the course of 2024. The ERC Consolidator Grant is highly coveted - this time, only 14.5 per cent of applications were approved. In Germany, Bielefeld University is second only to Ludwig-Maximilians-Universität München in the number of Consolidator Grants awarded in this round.

Physicists Dr. Olaf Kaczmarek and Dr. Christian Schmidt-Sonntag of Bielefeld University have secured 82 million core hours on the most powerful supercomputers in Europe. This will not only speed up the research process in their respective projects on heavy quarks in a plasma of quarks and gluons (Dr. Kaczmarek) and the phase diagram of quarks and gluons (Dr. Schmidt-Sonntag), but also highlight the importance of their work. The researchers’ findings will later be transferred to the Bielefeld supercomputer at the Bielefeld GPU Cluster and be made publicly accessible.

"COSMOfit" offers an introduction to space exploration with workshops and an Escape Game.
3 - 2 - 1 - Liftoff! The "COSMOfit" project has started in Bielefeld. Together with researchers from Bielefeld University and Bielefeld University of Applied Sciences (HSBI), Wissenswerkstadt Bielefeld offers an introduction to space research. In addition to children and young people, adults are also addressed.
The "COSMOmission" is an immersive "Escape Game" for which a room in the Volksbank Bielefeld-Gütersloh at the Kesselbrink was transformed into a spaceship cockpit. On the way to the star system Alpha Centauri, the players have to solve various puzzles in order to reach the destination - the fictitious Earth-like planet Gaia. In this way, scientific knowledge from space research is conveyed in an unusual and playful way. Researchers from the Faculties of Physics and Biology at Bielefeld University and researchers and students from the "Digital Media and Experiment" course at Bielefeld University were involved in the development.
In the "COSMOlabs", children and young people as well as adults slip into the role of space explorers and take a closer look at the universe. There are five different workshop topics, developed with researchers from the Faculties of Physics and Biology at the university. Why is it dark at night when there are such an unimaginable number of stars? And can micrometeorites actually be found in the dust from the roof of a university building? Participation in the "COSMOlabs" and the "COSMOmission" is free of charge. Dates are available until mid-December.

The German Federal Ministry of Education and Research (BMBF) is funding the joint project "Information Field Theory for Experiments on Large-scale Research Facilities" as part of its programme Exploring the Universe and Matter (ErUM). The working group of Prof. Dominik Schwarz at Bielefeld University is involved in this project. The project is coordinated by the Max Planck Institute for Astrophysics (Garching). Prof. Schwarz's group, together with colleagues from the University of Hamburg and the Technical University of Munich, will apply methods of information field theory to problems in radio astronomical imaging. Other project partners are RWTH Aachen, the University of Erlangen-Nuremberg, the Karlsruhe Institute of Technology, the Technical University of Munich, and the University of the Federal Armed Forces in Munich. Information field theory is a toolbox that allows to obtain a maximum amount of information about physical fields with the support of incomplete measurements and under consideration of measurement errors. In this ErUM-Data project, information field theory methods are further developed for radiation biology, radio astronomy and cosmic particle radiation.

Magnetic materials can be used as coolants in ordinary refrigerators or to reach ultracold temperatures to power quantum computers or space telescopes, for example.
Researchers from Herakleion, Edinburgh, Saragosa and Bielefeld have recently succeeded in synthesizing a new material based on gadolinium-containing molecules that has excellent cooling rates at temperatures between 1.5 K and 0.3 K. This is exactly the temperature range that is needed for applications in space telescopes.
The contribution of the Bielefeld-based working group Schnack consists in modeling the material with the support of advanced quantum mechanical methods.

Scientists at the Universities of Würzburg and Bielefeld detect the quantum properties of collective optical-electronic oscillations on the nanoscale. The results could contribute to the development of novel computer chips.
The Faculty of Physics invites all interested physics teachers to an open exchange on the topic "Physics in school" on March 21, 2023 (2:15 - 3:45 pm). Topics include (professional development) offers for teachers and students as well as the new "Kernlehrplan".
