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, ...

Researchers generated stable vortex light in its lowest-energy state using liquid crystal traps and optical confinement.

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 ...

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 ...

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 ...
