Fig. 1. The differences of electric fields (left) and magnetic fields (right) of the REVB between the spin-up (s = 1/2) and spin-down (s = –1/2) states, El,1/2(ρ) – El, – 1/2(ρ) and Bl,1/2,z(ρ) – Bl, – 1/2,z(ρ), vs. ρ for three cases: (a) l = 1, 5, 10, α = 0.7 rad, Ek = 0.2 MeV; (b) Ek = 0.2 MeV, 0.6 MeV, 1 MeV, l = 1, α = 0.7 rad; (c) α = 0.2 rad, 0.7 rad, 1.2 rad, l = 1, Ek = 0.2 MeV.

Linear momentum and angular momentum of the electromagnetic field of the relativistic EVBs, respectively, in spin-up (s = 1/2) and spin-down (s = –1/2) states vs (a) topological charge l for opening angle α = 0.7 rad, kinetic energy Ek = 0.2 MeV, (b) opening angle α for l = 1 rad, Ek = 0.2 MeV, (c) kinetic energy Ek for α = 0.7 rad, and l = 1.
