Airy beam: When an ordinary beam of neutrons strikes the team’s silicon grating, the millions of scored lines on the grating convert the neutrons into an Airy beam with a wavefront that travels along ...

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 ...

For SF works like "Star Wars", as a technique to attract spaceships and luggageTractor beam"Will appear. In reality, we succeeded in making a tractor beam that floats objects by floating ultrasonic ...

In a physics first, a team including scientists from the National Institute of Standards and Technology (NIST) has created a way to make beams of neutrons travel in curves. These Airy beams (named for ...

The key innovation of our propulsion concept is the unique coupling of a neutral particle beam with a laser beam, a scheme which nearly eliminates thermal expansion and diffraction during beam ...

Scientists may have discovered how to create a real-life tractor beam using electromagnetic radiation that can draw particles toward it. The result is something very akin to the tractor beam seen in ...

This animation shows how a hypothetical future mission might eventually employ ‘tractor beam’ technology. (Credit: NASA’s Goddard Space Flight Center, Conceptual Image Lab) Tractor beams — the ability ...
