Scientists used high magnetic fields and low temperatures to study crystals of URu2–xFexSi2. Using these conditions, they explored an intriguing state of matter called the "hidden order phase" that exhibits emergent behavior. Emergent behavior occurs when the whole is greater than the sum of its parts, meaning the whole has exciting properties that its parts do not possess; it is an important concept in philosophy, the brain and theories of life. This data provide strict constraints on theories of emergent behavior.
New materials that exhibit a strong coupling between magnetic and electric effects are of great interest for the development of high-sensitivity detectors and other devices. This paper reports on such a coupling in a specially designed material.
Researchers discover that Sr1-yMn1-zSb2 (y,z < 0.1) is a so-called Weyl material that holds great promise for building devices that require far less power.
This area of research could help scientists understand high-temperature superconductivity and other mysteries.
Controlled by electron interactions, the Mott transition is accompanied by a reduction in the volume of the atomic lattice.
Team opens new path for understanding hidden order.
