Researchers from Physikalisch-Technische Bundesanstalt (PTB), Technical University of Braunschweig, and the University of Delaware achieved new insight into the inner structure of the ¹⁷³Yb⁺, and in particular its nucleus. This could advance research in areas such as atomic clocks, tests of fundamental physics, and quantum information processing. The results are published in the latest issue of the renown scientific journal Physical Review Letters.

For the first time, a research group at the University of Potsdam has succeeded in tracking and quantifying the light-induced accumulation of charge on gold nanorods in real time. A new physical model of this process, describing nanoparticles as capacitors, is relevant to the development of sustainable procedures such as CO₂ reduction, water splitting, and solar energy conversion. The publication “Capacitive photocharging of gold nanorods” was published in Nature Communications and was recognized as “Editor’s Highlight”.

Scientists at the X-ray free-electron laser SwissFEL have realised a long-pursued experimental goal in physics: to show how electrons dance together. The technique, known as X-ray four-wave mixing, opens a new way to see how energy and information flow within atoms and molecules. In the future, it could illuminate how quantum information is stored and lost, eventually aiding the design of more error-tolerant quantum devices. The findings are reported in Nature.

A recent study published in Physical Review Letters and carried out by researchers from EHU, the Materials Physics Center, nanoGUNE, and DIPC introduces a groundbreaking approach to solar energy conversion and spintronics. The work tackles a long-standing limitation in the bulk photovoltaic effect—the need for non-centrosymmetric crystals—by demonstrating that even perfectly symmetric materials can generate significant photocurrents through engineered surface electronic states. This discovery opens new pathways for designing efficient light-to-electricity conversion systems and ultrafast spintronic devices.
