Abstract

The exact action of the Roentgen effect at an atomic level is investigated within the context of vortex formation using two Laguerre Gaussian beams. Starting from a modified Gross-Pitaevskii equation in the dipole approximation that takes into account the coupling of the atomic system to the electromagnetic fields the Roentgen interaction term is introduced and viewed within the context of such a Raman transition. A rigorous investigation of the corresponding Rabi frequency reveals that the Roentgen term acts at different levels compared to the (-d.E) term and thus would not cause any changes in a fully quantum mechanical treatment.
