Optical rogue waves reveal insight into real ones

(Phys.org)—Rogue waves in the middle of the ocean often appear out of nowhere and vanish just as quickly. But in their short lifetimes, they can generate walls of water 15 to 30 meters (50 to 100 feet) high, crashing down ...

Quantum vortex formation in the lab

Quantized vortices can be generated in classical experiments of liquid helium and ultracold dilute gases to conduct fundamental and comparative studies of different superfluids. In a new report published in Science Advances, ...

A vortex (plural: vortices) is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow. The motion of the fluid swirling rapidly around a center is called a vortex. The speed and rate of rotation of the fluid are greatest at the center, and decrease progressively with distance from the center.
