Researchers have observed three-dimensional magnetic vortex rings in a real-world magnetic material for the first time. Contrary to theoretical predictions, these rings – which are spin configurations ...

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, ...

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 ...

A century-old physics question had scientists and mathematicians in knots, until two researchers at the University of Chicago annihilated them. Dustin Kleckner, a postdoctoral scientist, and William ...

Air rings blown by dolphins swimming underwater and rings of smoke emitted by jet engines are just two examples of vortex rings. These doughnut-shaped structures and their mesmerizing movement have ...

So long, solitons: University of Chicago physicists have shown that a group of scientists were incorrect when they concluded that a mysterious effect found in superfluids indicated the presence of ...

Physics Girl is available to stream on pbs.org and the free PBS App, available on iPhone, Apple TV, Android TV, Android smartphones, Amazon Fire TV, Amazon Fire Tablet, Roku, Samsung Smart TV, 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 ...

Kleckner and William Irvine, assistant professor in physics, report their findings on the creation and dynamics of vortex rings in Nature Physics, published online on March 3. Their work relates to ...
