BUFFALO, N.Y. — In a physics first, a team including scientists from the University at Buffalo and the National Institute of Standards and Technology (NIST) has created a way to make beams of neutrons ...

Physicists have demonstrated accelerating light beams on flat surfaces, where acceleration has caused the beams to follow curved trajectories. However, a new experiment has pushed the boundaries of ...

If you shine a beam of light from a laser or flashlight, the beam will spread out over distance, becoming wider and less intense far from the source. That phenomenon is called diffraction, and it is ...
