A procedure to directly measure the strength of Landau damping

Landau damping, a phenomenon originally predicted by Lev Landau in 1946, is essential to ensure the collective beam stability in particle accelerators. By precisely measuring the strength of Landau damping, physicists can predict the stability of beams in high-energy colliders.

Scientists identify key trends in high-energy-density mixing layers

Imagine a bottle of salad dressing containing oil and vinegar. The oil has a lower density than vinegar, so it floats on the vinegar. The oil will not stay trapped under the vinegar if the bottle is flipped upside down. It will bubble up through the vinegar until a stable state is restored.

Crystalline supermirrors for trace gas detection in environmental science and medicine

In an international cooperation with partners from industry and research, physicists from the University of Vienna, together with Thorlabs, the National Institute of Standards and Technology (NIST), and the University of Kansas, have now succeeded for the first time in demonstrating high-performance laser mirrors in the sensing-relevant mid-infrared wavelength range that absorb less than ten out of a million photons. Manufactured in a new process based on crystalline materials, these low-loss mirrors promise to open up completely new application areas, for example in optical respiratory gas analysis for early cancer detection or the detection of greenhouse gases. This work will be published in the current issue of the journal Optica.

Scientists get photons to interact, taking a step towards long-living quantum memory

Scientists believe that individual light particles, or photons, are ideally suited for sending quantum information. Encoded with quantum data, they could literally transfer information at the speed of light. However, while photons would make for great carriers because of their speed, they don't like to interact with each other, making it difficult to achieve quantum entanglement.

Spintronics: Improving electronics with finer spin control

Spintronics is an emerging technology for manufacturing electronic devices that take advantage of electron spin and its associated magnetic properties, instead of using the electrical charge of an electron, to carry information. Antiferromagnetic materials are attracting attention in spintronics, with the expectation of spin operations with higher stability. Unlike ferromagnetic materials, in which atoms align along the same direction like in the typical refrigerator magnets, magnetic atoms inside antiferromagnets have antiparallel spin alignments that cancel out the net magnetization.

Astronomy and Space news

Deep water on Neptune and Uranus may be magnesium-rich

While scientists have amassed considerable knowledge of the rocky planets in our solar system, like Earth and Mars, much less is known about the icy water-rich planets, Neptune and Uranus.

Reseachers detect a new ultra-metal-poor star

Astronomers report the discovery of a new ultra-metal-poor star as part of the Southern Photometric Local Universe Survey (S-PLUS). The newly found star, designated SPLUS J210428.01−004934.2, turns out to have the lowest carbon abundance among the ultra-metal-poor stars so far detected. The finding is detailed in a paper published May 10 on the arXiv pre-print repository.

Stunning simulation of stars being born is most realistic ever

A team including Northwestern University astrophysicists has developed the most realistic, highest-resolution 3D simulation of star formation to date. The result is a visually stunning, mathematically-driven marvel that allows viewers to float around a colorful gas cloud in 3D space while watching twinkling stars emerge.

'Europium stars' in the dwarf galaxy Fornax lend new insight into the origin of the elements

Europium is the key for understanding the formation of the heavy elements by the fast neutron capture process, the so-called r-process. This is crucial both for the formation of half of the elements heavier than iron and for the total abundance of thorium and uranium in the universe. The EUROPIUM group has combined theoretical astrophysical simulations with observations of the oldest stars in our Galaxy and in dwarf galaxies. The latter are small, dark-matter dominated galaxies orbiting our Galaxy. Dwarf galaxies are excellent test objects for studying the r-process, as some of the oldest metal-poor stars, those that have existed for 10 to 13 billion years, have exhibited an overabundance of r-process elements. Studies have even postulated that only a single neutron-rich event could be responsible for this enrichment in the smallest dwarf galaxies.

Observatory discovers a dozen PeVatrons and photons exceeding 1 PeV, launches ultra-high-energy gamma astronomy era

China's Large High Altitude Air Shower Observatory (LHAASO)—one of the country's key national science and technology infrastructure facilities—has found a dozen ultra-high-energy (UHE) cosmic accelerators within the Milky Way. It has also detected photons with energies exceeding 1 peta-electron-volt (quadrillion electron-volts or PeV), including one at 1.4 PeV. The latter is the highest energy photon ever observed.

Researchers find stratified structure in broad-line region for changing-look active galactic nuclei
