Physical effect also valid in the quantum world
Physical effect also valid in the quantum world
Researchers at the University of Bonn confirm validity of a central theorem of physics for Bose-Einstein condensates Physicists at the University of Bonn have experimentally proven that an important theorem of statistical physics applies to so-called "Bose-Einstein condensates." Their results now make it possible to measure certain properties of the quantum "superparticles" and deduce system characteristics that would otherwise be difficult to observe.

Researchers gain deeper understanding of mechanism behind superconductors
Physicists at Leipzig University have once again gained a deeper understanding of the mechanism behind superconductors. This brings the research group led by Professor Jürgen Haase one step closer to their goal of developing the foundations for a theory for superconductors that would allow current to flow without resistance and without energy loss.

Swarm Intelligence Caused by Physical Mechanisms
Seemingly spontaneously coordinated swarm behaviour exhibited by large groups of animals is a fascinating and striking collective phenomenon. Experiments conducted by researchers at Leipzig University on laser-controlled synthetic microswimmers now show that supposed swarm intelligence can sometimes also be the result of simple and generic physical mechanisms.

COMPASS for Highly Sensitive Rapid Tests
A newly developed rapid test needs only a few seconds to reliably detect pathogens such as SARS-CoV-2. It is based on specially designed magnetic nanoparticles. The current rapid tests for diagnosing infectious diseases are speedy, but not really fast. For example, antigen self-tests, PCR tests or ELISA tests for coronavirus take 15 minutes to several hours before a reliable result is available.

Antihelium nuclei as messengers from the depths of the galaxy
New findings lay the foundation for the search for dark matter How are galaxies born, and what holds them together? Astronomers assume that dark matter plays an essential role. However, as yet it has not been possible to prove directly that dark matter exists. A research team including Technical University of Munich (TUM) scientists has now measured for the first time the survival rate of antihelium nuclei from the depths of the galaxy - a necessary prerequisite for the indirect search for Dark Matter.

Confident x-ray analysis
In future it will be possible to incorporate data from deep space telescopes into the underlying atomic models with a high degree of reliability Very hot gas, as found in the sun's corona or in close proximity to black holes, emits very intense x-rays. It reveals the locally prevailing physical conditions, such as temperature and density.

Curved spacetime in the laboratory
Curved spacetime in the laboratory
Scientists simulate a whole family of universes with curvature in ultracold quantum gases According to Einstein's general theory of relativity, space and time are inseparable. In our universe - which is hardly measurably curved - the structure of this spacetime is predetermined. Scientists at Heidelberg University have now succeeded in realizing an effective spacetime in a laboratory experiment that can be manipulated.

New way to produce important molecular entity
Chemists at the University of Münster develop method for simple production of vicinal diamines Among the most common structures relevant to the function of biologically active molecules, natural products and drugs are so-called vicinal diamines - in particular, unsymmetrically constructed diamines. Vicinal diamines contain two functional atomic groups responsible for the substance properties, each with a nitrogen atom bonded to two neighbouring carbon atoms.

New Scientific Finding: Light Can Be Used to Control Molecular Handedness
Researchers at Freie Universität Berlin took part in a new study on chiral molecules recently published in "Science Advances" In a recent study, researchers at Freie Universität Berlin, the DESY research center in Hamburg, Kiel University, and Kansas State University have shown how light can turn a planar molecule into a chiral molecule with just one particular handedness, providing a solution to the long-standing problem of absolute asymmetric synthesis.

Energy-efficient computing with tiny magnetic vortices
Unconventional computing combines Brownian computing with reservoir computing / First prototype developed A large percentage of energy used today is consumed in the form of electrical power for processing and storing data and for running the relevant terminal equipment and devices. According to predictions, the level of energy used for these purposes will increase even further in the future.

Long-range information transport in antiferromagnets
Long-range information transport in antiferromagnets
Antiferromagnets are suitable for transporting spin waves over long distances Smaller, faster, more powerful: The demands on microelectronic devices are high and are constantly increasing. However, if chips, processors and the like are based on electricity, there are limits to miniaturization. Physicists are therefore working on alternative ways of transporting information, such as about spin waves, also called magnons, for example.

Detecting defects in semiconductors at the atomic level
Modern solar cells work with thin layers of semiconductors that convert sunlight into electrical energy. The key to increasing their efficiency even further lies in the composition and structure of the material. Due to the way the material is manufactured, it can have defects that have a disruptive effect.

A sustainable path for energy-demanding photochemistry
Researchers in Mainz and Kyushu established a novel strategy for the generation of highly energetic UV light Many photochemical processes rely on UV light from inefficient or toxic light sources that the LED technology cannot replace for technical reasons. An international team of scientists led by Professor Christoph Kerzig of Johannes Gutenberg University Mainz (JGU) in Germany and Professor Nobuhiro Yanai of Kyushu University in Japan has now developed the first molecular system for the conversion of blue light into high-energy UV photons with wavelengths below 315 nanometers.
