One-fifth of global electricity consumption is based on lighting; efficient and stable white-light emission with single materials is ideal for applications. Photon emission that covers the entire visible spectrum is, however, ...
In classical mechanics, particles are represented by point masses or rigid bodies, and in field theory by wave-like excitations or vibrations. Magnetic skyrmions are small, vortex-like spin textures of topological origin ...
Perfectly inverting complex structures is of great technical importance. Researchers at ETH have now succeeded in turning the magnetic and electric structure of materials into their opposites using a single magnetic field ...
For the first time, researchers were able to study quantum interference in a three-level quantum system and thereby control the behavior of individual electron spins. To this end, they used a novel nanostructure in which ...
Topology is a global aspect of materials, leading to fundamental new properties for compounds with large relativistic effects. The incorporation of heavy elements gives rise to non-trivial topological phases of matter, such ...
The exact science of tree sap transport has puzzled plant physiologists for many years. Sap's migration throughout tree trunks and branches is linked heavily to transpiration, the movement and subsequent evaporation of moisture ...
Brown University researchers and collaborators from Tsinghua University in China have shown that nanoclusters made from boron and lanthanide elements form highly stable and symmetric structures with interesting magnetic properties.
A massless particle, a.k.a. Weyl fermion, predicted nearly 100 years ago, has been found in another corner of physics. Electrons in a semimetal can behave like these particles. They are either right-handed or left-handed—they ...
The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. But finding or designing materials that can host such quantum interactions ...
A research team from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has found the first evidence that a shaking motion in the structure of an atomically thin (2-D) material possesses a naturally ...
