Optical vortices (OVs) ?also refered to as Twisted Light? are complex electromagnetic fields with unique properties, such as points where the phase cannot be defined (phase singularities) and a well-defined value of orbital angular momentum (AM). Important realizations of OVs, such as Bessel and Laguerre-Gauss beams, posses cylindrical symmetry. Therefore, the archetypical model that captures the essential features of lightmatter interaction in solid-state physics is the one-dimensional semiconductor Quantum Ring (QR).In this presentation we will show how Eq. (1) is derived from the simplification introduced by the MQS approximation, and analyze in detail its meaning, as well as its analogies and differences with the semiconductor Bloch equation for excitons.
