We explore photon vortex generation in synchrotron radiations from a spiral
moving electron under a uniform magnetic field along z-axis using Landau
quantization. The obtained wave-function of the photon vortecies is the
eigen-state of the z-component of the total angular momentum (zTAM). In m-th
harmonic radiations, individual photons are the eigen-state of zTAM of m. This
is consistent with previous studies. Using the presently obtained
wave-functions we calculate the decay widths and the energy spectra under
extremely strong magnetic fields of 10^12 – 10^13 G, which are observed in
astrophysical objects such as magnetized neutron stars and jets and accretion
disks around black holes. The result suggests that photon vortices are
predominantly generated in such objects. Although they have no coherency it is
expected that photon vortices from the universe are measured using a detector
based upon a quantum effect in future. This effect also affects to stellar
nucleosynthesis in strong magnetic fields.
