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 ...

University of Chicago 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 ...

A vortex is a physics phenomenon that occurs when a gas or a liquid moves in circles. At the center is a vortex line that the matter swirls around. They are formed when there is a difference in the ...

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 ...

You probably have seen smoke rings blown by cigarette smokers or bubble rings from playful dolphins. But do you know that they are closely related to each other and officially known as the vortex ring ...
