In recent decades, the facilities with radioactive ion beam models to study nuclear magnetic moments make it possible to measure the magnetic moments of neutron-rich and proton-rich nuclei with high precision.
On the theoretical side, many nuclear structure models, including advanced shell models, and self-consistent mean-field theories, have succeeded analyzing many nuclear structure properties. However, the extension of these models to the study of nuclear magnetic moments is quite limited and unsatisfactory. The magnetic dipole moments of most atomic nuclei throughout the periodic table still remain unexplained and the under-lying physics mechanism is not fully understood.
In view of these facts, SCIENCE CHINA: Physics, Mechanics & Astronomy editorial board has invited a number of major theoretical nuclear physicists in the research field of nuclear magnetic moments and related topics to contribute to this special topic. However, due to the page limitation the discussion on the topic presents just a fraction of the progress in this field.
This special issue on "Nuclear magnetic moments and related topics" consists of ten selected papers, which review the progress not only on the theoretical description of nuclear magnetic moments, but also on the recent development of closely related subjects including nuclear pairing, quantum phase transitions as well as nuclear masses in microscopic models. This issue is also intended to identify common goals to deepen understanding of nuclear structure.
In summary, theoretical description of nuclear magnetic moments is one of the long-standing subjects. More important progress will be made in the near future.

Gravitational wave kicks monster black hole out of galactic core

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
