New Anglo-German generative model is more efficient than established approaches.

Physicists and materials scientists can choose from a whole family of computer codes that simulate the behavior of materials and predict their properties. The accuracy of the results obtained by t ...

Bringing protons up to speed with strong laser pulses – this still young concept promises many advantages over conventional accelerators. For instance, it seems possible to build much more compact facilities.

Bringing protons up to speed with strong laser pulses – this still young concept promises many advantages over conventional accelerators. For instance, it seems possible to build much more compact facilities. Prototypes to date, however, in which laser pulses are fired at ultra-thin metal foils, show weaknesses – especially in the frequency with which they can accelerate protons. At the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), an international working group has tested a new technique: In this approach, frozen hydrogen acts as a "target" for the laser pulses. In the future, the ...

The arrangement of electrons in matter, known as the electronic structure, plays a crucial role in fundamental but also applied research such as drug design and energy storage. However, the lack of a simulation technique that offers both high fidelity and scalability across different time and length scales has long been a roadblock for the progress of these technologies.
