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 ...

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 ...

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

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 ...

Collisions in high-energy ion beams reduce the beam intensity and can be remedied by extra focusing devices or the use of low-density beams. However, physicists predicted 20 years ago that in a ...

CONSTRUCTED. >> WE ARE IN BLAIR COUNTY AND THIS IS THE PLANT RESPONSIBLE FOR MAKING THE BEAMS HEADED TO FERN HOLLOW. THIS IS ONE OF THEM. THESE ARE HIGH-PERFORMANCE CONCRETE BEAMS. IT IS ABOUT 155 ...

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 ...
