Bucht jetzt euren „Sterne und Kerne-Projekttag“ und erlebt Forschung hautnah!

Wie arbeitet man eigentlich in der modernen Forschung? Beim Projekttag des Sonderforschungsbereichs 1245 können Schulklassen genau das herausfinden und selbst Teil eines Forschungsteams werden.

Prof. Takashi Nakamura was the lecturer of our Experimental Topical Lecture Week in Spring2026 and presented Lectures on “Neutron-rich nuclei and multi-neutron systems probed by experiments with rare-isotope beams” to the young researchers of the SFB.

Tobias Wolfgruber defended his dissertation entitled “Precision No-Core Shell Model Calculations with Artificial Neural Networks” successfully. Congratulations.

Innovative machine learning uses data of neutron stars

Which complex forces operate in atomic nuclei? A research team with participation of TU Darmstadt has used astrophysical explosions to understand them better. The results were published in the prestigious journal „Nature Communications“.

Melissa Mendes was selected as the new FRIB theory fellow. Her research focuses on probing the nuclear matter equation of state (EOS), combining the results of low-energy nuclear experiments, astrophysical observables, and ab initio calculations. She is currently supported from the ERC Advanced Grant EUSTRONG and a member of the SFB 1245. She will begin her new position at FRIB in November 2026. Congratulations from the whole team of SFB 1245.

Challenges in effective field theory descriptions of nuclei

From January 18-24, 2026 the EMMI Hirschegg Workshop, co-organized by SFB 1245 project leaders, was held in Hirschegg on the topic “Challenges in effective field theory descriptions of nuclei”. Many excellent junior and senior speakers from different fields discussed new developments on new nuclear interactions and uncertainty quantification, universality in nuclei and multi-neutron systems, heavy nuclei and deformation, electroweak interactions in nuclei as well as collective phenomena.

New findings published in Physical Review Letters

The publication “Impact of ground-state correlations on the multipole response of nuclei: Ab initio calculations of moment operators” (Phys. Rev. C 112, 054303) was highlighted as Editor's Suggestion.

TU Researchers publish study on triaxial structures

Laser Spectroscopy can be used to determine the relative size of different atomic nuclei of the same element by measuring tiny changes in their atomic spectra. We set up a novel apparatus for such experiments at Argonne National Laboratory and were able to reach outstanding sensitivity. These new developments allowed us to investigate the size of a series of radioactive ruthenium nuclei, which are known to be triaxial in shape: Similar to a coffee bean or an almond, all three axes have a different proportion.

Jörn Kleemann (B02) received a “Giersch Award 2025 for an Outstanding Doctoral Thesis” and Julian Palmes (A03) won a “Giersch-Excellence Award 2025”. Congratulations to our award winners!
