- Abstract: We study the photon emission by charged spinless particles with phase vortices and an orbital angular momentum (OAM) projection in longitudinal electric and magnetic fields within the scalar QED. A realistic wave packet of an electron or ion accelerated by a radio-frequency wave locally feels a constant and spatially homogeneous field, which allows us to develop an effective model for losing the angular momentum of the vortex particle due to photon emission. For the fields typical for accelerator facilities, we find that an effective lifetime of the vortex state greatly exceeds the acceleration time. This proves that the acceleration of vortex electrons, ions, muons, and so forth to relativistic energies is possible in conventional linacs, as well as in the wake-field accelerators with higher field gradients, the OAM losses due to the photon emission are mostly negligible, and that the vortex quantum state is highly robust against these losses.

Interband transitions of electrons in a gapped graphene monolayer are highly stimulated near the Fermi surface when a strong constant electric field is superposed in the plane of the flake.
We consider this phenomenon equivalent to the Franz-Keldysh effect, paying particular attention to the regime where the photon energy linked to the fast-oscillating field is just below the graphene gap.
