Visualizing the topology of electrons with '3D glasses'

They are seen as a beacon of hope for energy-saving electronics and the high-tech of the future: topological quantum materials. One of their properties is the conduction of spin-polarized electrons on their surface—even ...

Dynamical dark energy might explain strange 21-cm signal

Dark energy may evolve in time, and it may even connect through a new force of nature with dark matter. A researcher believes that we may have already seen evidence for this. Their findings have been reported on the preprint ...

Study offers improved air pollution understanding in China

Air pollution in China is generated from many sources and interacts chemically and physically within the atmosphere in ways that can be difficult to predict. The concept of the Air Pollution Complex was created to address ...

Quantum materials: Electron spin measured for the first time

An international research team has succeeded for the first time in measuring the electron spin in matter—i.e., the curvature of space in which electrons live and move—within "kagome materials," a new class of quantum ...
