First observation of a focused plasma wave on the sun
For the first time, scientists have observed plasma waves from a solar flare focused by a coronal hole, akin to the focusing of sound waves responsible for the Rotunda effect in architecture or the focusing of light by a ...
Collisions change how fast ions surf on plasma waves in fusion experiments and beyond
Just like there are waves in the ocean, waves can also occur in an electrically charged gas called a plasma, made up of electrons and ions. In the ocean, people surf by riding their boards at nearly the same speed as the ...

Manipulating superconducting plasma waves with terahertz light
Most systems in nature are inherently nonlinear, meaning that their response to any external excitation is not proportional to the strength of the applied stimulus. Nonlinearities are observed, for example, in macroscopic ...

Novel algorithm improves understanding of plasma shock waves in space
Imagine the explosive disturbance caused by a jet going supersonic. A similar shock wave occurs when subatomic particles known as "solar wind" flow from the sun and strike the Earth's magnetic field. Now, scientists have ...
