| 内容記述 | Light vortices carrying large angular momenta are interesting for fundamental physics study and applications. Recently, the phase structure of high-order harmonic radiations from spiral motion electrons under magnetic felds was calculated in classical electromagnetism [9]; this result suggests that a l-th harmonic photon is the photon vortex carrying lℏ total angular momentum. However, the problem of whether each single photon has a wave-function of a photon vortex has been an open question in quantum level. Here we show the photon generated by high-order harmonic radiations from a spiral motion electron under uniform magnetic felds is the photon vortex with the Bessel wave-function in quantum mechanics. We also present the decay widths from electrons in Landau levels and the energy spectra. The present result suggests a possibility that photon vortices are predominantly generated in astrophysical environments with strong magnetic felds such as magnetars or magnetized accretion disks around black holes. |
