The knots in your shoelaces are familiar, but can you imagine knots made from light, water, or from the structured fluids ...

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, ...

A major European research effort is beginning as Tampere University leads a €4.4 million Doctoral Network focused on high-power optical vortices, a form of twisting light with remarkable potential.

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 ...

A new laser based on a swirling vortex of light has been created by physicists in the US. The “topological-defect laser” could be a useful addition to lab-on-a-chip devices, where it could manipulate ...

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 ...

The physics association from the department of physics, Panjab University, in association with IAPT (Indian Association of Physics Teachers) organized its annual academic meet "Vortex 2013" on Tuesday ...

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 ...
