TL;DR: Bialynicki-Birula et al. as mentioned in this paper showed that the transverse motion of electrons in a beam is confined under the action of the electromagnetic wave alone: no additional attraction center is required.
Abstract: Our previous work (I. Bialynicki-Birula, Phys. Rev. Lett. 93 , 20402 (2004)) is extended to cover more realistic examples of electromagnetic waves, i.e., the Bessel beams. It is shown that electrons may be guided by a Bessel beam with nonvanishing orbital angular momentum. The mechanism for trapping the elec- trons near the electromagnetic vortex line of such a wave field is the same as for the Trojan states of Rydberg electrons produced by a circularly polarized wave. The main difference is that, in the present case, the transverse motion of electrons in a beam is confined under the action of the electromagnetic wave alone: no additional attraction center is required. We also discuss briefly the motion of electrons in Neumann and Hankel beams.
