Scientists in Germany have crafted “skyrmion bags” of light—complex vortex-like structures—on the surface of gold by cleverly ...

Light can tie knots—literally. Engineers at Duke University have managed to manipulate laser beams to form intricate 3D patterns called optical knots, using custom-designed optics. These twisted beams ...

Scientists have demonstrated a sort of holographic strip that splits a single laser beam into five bespoke beams that create an optical knot. The work shows that optical knots could be used as a ...
