A high energy electron in circular/spiral motion radiates vortex photons in the entire wavelength range from the radio-wave to the gamma-rays, researchers have shown theoretically and experimentally.

Chiral phonons are vibrations where atoms move in a circular pattern when energized, for example, by heat. As these vibrations travel through a material, they carry and spread tha ...

Learn how to calculate the speed of a mass in a circular pendulum with this clear physics tutorial! Step-by-step explanations make it easy to understand circular motion, energy, and angular velocity.

In the beam of light emitted by a laser pointer, photons travel predominantly along one direction and the beam is therefore said to be collimated. The electric field carried by these photons is ...
