Using data from the British neutron source ISIS from the year 2000, research teams have now demonstrated the viability of a “quantum entanglement witness” capable of proving the presence of entanglement between magnetic particles, or spins, in a quantum material. A team from HZB led by Prof. Bella Lake was also involved in the analysis.

- MAX IV and BESSY II initiate new collaboration to advance materials scienceSwedish national synchrotron laboratory MAX IV and Helmholtz-Zentrum Berlin (HZB) BESSY II light source jointly announce the signing of a 5-year Memorandum of Understanding (MoU). The new MoU establishes a framework to strengthen cooperation for operational and technological development in the highlighted fields of accelerator research and development, beamlines and optics, endstations and sample environments as well as digitalisation and data science.
- Michael Naguib is visiting HZB as a Humboldt Research AwardeeProfessor Michael Naguib, from Tulane University in the USA, is one of the discoverers of a new class of 2D materials: MXenes are characterised by a puff pastry-like structure and have many applications, such as in the production of green hydrogen or as storage media for electrical energy. During his Humboldt Research Award in 2025, Professor Naguib is working with Prof Volker Presser at the Leibniz Institute for New Materials in Saarbrücken and with Dr Tristan Petit at HZB.
- AI in Chemistry: Study Highlights Strengths and WeaknessesHow well does artificial intelligence perform compared to human experts? A research team at HIPOLE Jena set out to answer this question in the field of chemistry. Using a newly developed evaluation method called “ChemBench,” the researchers compared the performance of modern language models such as GPT-4 with that of experienced chemists.
