Researchers have developed a novel method to track light fields directly within optical resonators. This enables precise measurements at the exact locations where future field-resolved studies of light-matter interactions will take place.

Scientists from the Department of Physical Chemistry at the Fritz-Haber Institute of the Max Planck Society and the Helmholtz-Zentrum Dresden-Rossendorf have developed a new experimental platform to measure the electric fields of light trapped between two mirrors with precision below a light cycle. These electro-optical Fabry-Pérot resonators allow for precise control and observation of light-matter interactions, particularly in the terahertz (THz) spectral region.

Through the development of a tunable hybrid resonator design and the measurement and modeling of its complex mode spectrum, physicists can now actively switch between nodes and maxima of light waves at relevant resonator locations. This study thus opens new paths for the exploration of quantum electrodynamics and the ultrafast control of material properties.

➀ The U.S. Defense Advanced Research Projects Agency (DARPA) has selected two research teams, the University of Illinois Urbana-Champaign and Caltech, to advance in-space manufacturing under the NOM4D programme.

➁ The third and final phase of NOM4D will involve orbital demonstrations to evaluate materials and assembly processes in space.

➂ The NOM4D programme aims to overcome space cargo constraints and enable in-orbit construction of larger and more mass-efficient structures.

The Fraunhofer IZM, in collaboration with international partners, is working on a new injection molding process as part of the EU Horizon project MULTIMOLD. This process aims to produce environmentally friendly electronics products with maximum design freedom. The focus is on sustainability, including comprehensive life cycle assessments and optimizing resource use in the production process.

The project aims to improve the recyclability of products and reduce their ecological footprint, particularly by developing new methods for separating and reusing the individual layers of the components. The process is currently under development and is being continuously optimized for sustainable production without compromising the performance of electronic products.

➁ The project will be led by Päivi Törmä of Aalto University, focusing on quantum geometry in 3D materials;

➂ Artificial intelligence will be used to predict material properties for revolutionary levels of superconductivity.

➀ Researchers at TU Wien have discovered a new physical phenomenon that exists between metals and insulators, which they describe as a 'quantum umbilical cord.';

➁ This phenomenon occurs when the interaction strength between electrons is sufficiently large, leading to additional energy states between metallic and insulating materials;

➂ The discovery opens up new perspectives in material science and technology, suggesting that there are more states between conductors and insulators than previously thought.
