Dark state atom mirrors based on artificial gauge fields created by surface optical vortices

Aldossary, V. E. Lembessis, A. Al Rsheed, A. Lyras, and O. M. . 2019

We propose the construction of an atom mirror for cold three-level atoms in a dark state where the forces, responsible for the atomic reflection, are provided by artificial gauge fields. These fields are created from the total internal reflection of optical vortex beams with Gaussian intensity profiles at the interface of a dielectric prism and vacuum. We investigate the role of the photon angular momentum in the magnitude of these fields and consequently on the efficiency of atomic reflection.

We present the theoretical framework and the approximations needed to numerically simulate the response of alkali metal atoms under multi-photon excitation.

We report theoretical results for the transition amplitudes of two-photon transitions induced in a one-active-electron atomic system by a LG10 beam. We identify the excitation pathways for…

We investigate the quantized states of a two-level Rb atom that is trapped by the optical dipole potential when the atom interacts with a helical optical tube light field.
