Vortex photons from electrons in circular motion

(National Institutes of Natural Sciences) Researchers at IMS and their coworkers have shown theoretically and experimentally that a high energy electron in circular/spiral motion radiates vortex photons in the entire wavelength range from the radio-wave to the gamma-rays. This greatly broadens application spectra of the vortex photons in the field of physical science. Moreover, the finding indicates that vortex photons are ubiquitous in the universe. It paves a way to a completely new research f
