After 20 years, jet diffusion wakes detected in quark-gluon plasmas
Boats passing over smooth water form a pair of diffusion wakes behind them veering off at a certain angle. Turbulence occurs along the line directly behind the boat, but the two diffusion waves are at a theoretical angle ...
Laser experiments recreate solar flare physics and reveal consistent magnetic reconnection rates
Magnetic reconnection is a process that occurs when the magnetic fields of a conductive plasma quickly rearrange and release massive amounts of stored magnetic energy. It is widely thought to be the underlying mechanism behind ...
