New ATLAS result weighs in on the W boson
Physicists present new result of the ATLAS detector The W boson is the mediator particle of the electroweak force. Discovered in the 1980s at CERN, its properties remain challenging to measure within the Standard Model of particle physics. An international team has now presented a new and improved W-boson mass measurement by the ATLAS experiment at CERN.

Surprise in the Quantum World
Researchers from the Cluster of Excellence ct.qmat have achieved a significant milestone in the pursuit of energy-efficient quantum technologies by designing a ferromagnetic topological insulator. In 2019, an international research team headed by materials chemist Anna Isaeva, at that time a junior professor at ct.qmat (Complexity and Topology in Quantum Matter), caused a stir by fabricating the world's first antiferromagnetic topological insulator - manganese bismuth telluride (MnBi 2 Te4).

Smart light traps
Synthesis gas and battery power from sunlight energy Plants use photosynthesis to harvest energy from sunlight. Now researchers at the Technical University of Munich (TUM) have applied this principle as the basis for developing new sustainable processes which in the future may produce syngas (synthetic gas) for the large-scale chemical industry and be able to charge batteries.

Magnifier for quantum excitations
Scientists at TU Ilmenau have succeeded in realizing and understanding in detail a molecular magnifying glass for the lattice vibrations of a two-dimensional material. The results of the work, which are the result of many years of intensive joint research with theoretical physicist Mads Brandbyge from TU Denmark, have just been published in Physical Review Letters , the most important journal for physics research.

Understanding quantum mechanics with active particles
Physicists discover unexpected connection between active particles and quantum-mechanical systems The study of active particles is one of the fastest-growing areas of physics. With "active particles" physicists refer to objects which move by themselves as a result of internal self-propulsion. These include living things such as bacteria and fish swimming, birds flying or humans walking around - as well as artificial nano-robots which can be inserted into the body to transport medication.

Hotter than infinity - Light pulses can behave like an exotic gas
In our modern society huge amounts of data are transmitted every day, mainly as short optical pulses propagating through glass fibres. With the steadily increasing density of such optical signals, their interaction grows, which can lead to data loss. Physicists at the Friedrich Schiller University Jena and the College of Optics and Photonics in Orlando, Florida are investigating how to control large numbers of optical pulses as precisely as possible to reduce the effect of such interactions.

Access to new fluorescent materials
Significantly increased efficiency of fluorescence - Wide range of applications in everyday life Fluorescence is a fascinating natural phenomenon. It is based on the fact that certain materials can absorb light of a certain wavelength and then emit light of a different wavelength. Fluorescent materials play an important role in our everyday lives, for example in modern screens.

Honeycombs in the desert
Convection of salty water creates hexagonal patterns The honeycomb-like patterns that often occur in salt deserts, including Death Valley and Chile, look like something from another world. A team that included researchers from the Max Planck Institute for Dynamics and Self-Organization in Göttingen, Germany, explain the origin of the mysterious patterns for the first time.

Method found for analysing complex, tiny crystals
The atomic structure of solid substances can often be analysed quickly, easily and very precisely using X-rays. However, this requires that crystals of the corresponding substances exist. Chemist Professor Oliver Oeckler from Leipzig University and his team are developing methods to make this possible even for very small crystals that cannot be seen with the naked eye.
