University of Chicago physicists have succeeded in creating a vortex knot—a feat akin to tying a smoke ring into a knot. Linked and knotted vortex loops have existed in theory for more than a century, ...

Vortex arrays in type-II superconductors reflect the translational symmetry of an infinite system. There are cases, however, such as ultracold trapped Fermi gases and the crust of neutron stars, where ...

This calculated diffraction image shows how forked diffraction gratings shape the atoms' wave function into a vortex. (Courtesy: Science/AAAS) A wave-like property previously only seen in beams of ...

Turbulent ball: William Irvine, Takumi Matsuzawa and colleagues have used this apparatus to track turbulence with lasers and high-speed cameras. (Courtesy: Takumi Matsuzawa) Researchers in the US have ...

Physicists have succeeding in creating a vortex knot -- a feat akin to tying a smoke ring into a knot. Linked and knotted vortex loops have existed in theory for more than a century, but creating them ...

This appendix introduces the study of vortex matter and describes some of the leading avenues of research. The experimental exploration of vortex matter, which is one of the many topics uncovered by ...

The same physics that gives tornadoes their ferocious stability lies at the heart of new research, and could lead to a better understanding of nuclear dynamics in studying fission, superconductors and ...

Video: Thousands of computer processors working together are needed to produce these detailed simulations of turbulent vortices. State-of-the-art computer graphic systems developed for movies and ...

A giant quantum vortex may allow researchers to study black holes. This vortex is an eddy in a special form of liquid helium that displays quantum effects. The result has some properties similar to ...

Here you see the good folks on QI shooting smoke rings across the room. Why does a donut-shaped cloud come out of a circular opening? Why are smokers able to blow smoke rings, even when they’re not ...
