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 ...

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 ...

Bright idea: researchers in China have found a new way to accelerate electrons using pulses of light. (Courtesy: iStock/7io) A laser wakefield accelerator (LWFA) that guides its laser beams along ...

There are many applications for particle accelerators, even outside research facilities, but for the longest time they have been large, cumbersome machines, not to mention very expensive to operate.

Lasers may have thousands of applications in every section of modern society, but all laser beams are fundamentally similar – single-coloured and straight. Now, US physicists have helped to break that ...

Scientists have created the first neutron 'Airy beam,' which has unusual capabilities that ordinary neutron beams do not. The achievement could enhance neutron-based techniques for investigating the ...
