Stuck in the rough: How aging reactor walls may exhibit lower erosion
As plasma circulates in a fusion device, the surface of the device that faces the plasma erodes. This releases particles of surface material. Most erosion occurs through a process called sputtering, where a particle strikes ...

Interaction-free, single-pixel quantum imaging with undetected photons
To capture an image of an object, a photographer typically requires a source of light interacting and scattering away from that object of interest, and a method to detect the light being scattered away from that object, as ...
Researchers devise a new path toward 'quantum light'
Researchers have theorized a new mechanism to generate high-energy "quantum light," which could be used to investigate new properties of matter at the atomic scale.
