A novel technique for identifying magnetic ordering in antiferromagnets

A new trick for illuminating the internal ordering within a special type of magnet could help engineers build better memory-storage devices. Developed by RIKEN physicists, this technique could make memory devices less corruptible.

Atomic traffic control—researchers develop novel technology for more precise quantum sensors

Quantum sensors can be significantly more precise than conventional sensors and are used for Earth observation, navigation, material testing, and chemical or biomedical analysis, for example. TU Darmstadt researchers have now developed and tested a technique that makes quantum sensors even more precise.

Simulations reveal Anderson transition for light in 3D disordered systems

The Anderson transition is a phase transition that occurs in disordered systems, which entails a shift from a diffusive state (i.e., in which waves or particles are spread out) to a localized state, in which they are trapped in specific regions. This state was first studied by physicist Philip W. Anderson, who examined the arrangement of electrons in disordered solids, yet it was later found to also apply to the propagation of light and other waves.

From collisions to stellar cannibalism—the surprising diversity of exploding white dwarfs

Astrophysicists have unearthed a surprising diversity in the ways in which white dwarf stars explode in deep space after assessing almost 4,000 such events captured in detail by a next-gen astronomical sky survey. Their findings may help us more accurately measure distances in the universe and further our knowledge of “dark energy.”

White dwarf stars may host more habitable exoplanets than expected

Among the roughly 10 billion white dwarf stars in the Milky Way galaxy, a greater number than previously expected could provide a stellar environment hospitable to life-supporting exoplanets, according to astronomers at the University of California, Irvine.

Greetings from the fourth dimension: Scientists glimpse 4D crystal structure using surface wave patterns

In April 1982, Prof. Dan Shechtman of the Technion–Israel Institute of Technology made the discovery that would later earn him the 2011 Nobel Prize in Chemistry: the quasiperiodic crystal. According to diffraction measurements made with an electron microscope, the new material appeared “disorganized” at smaller scales, yet with a distinct order and symmetry apparent at a larger scale.
