Opticalvortices (OV) are electromagnetic fields with surprising propertiessuch as phase singularities, orbital angular momentum (AM), etc. Wheninteracting with matter, their peculiar properties can be used toexcite unusual transitions. In this contribution we discuss differentkinds of OV and analyze their capability of controlling excitonstates in circularly symmetric semiconductor quantum dots (QD), basedon a configuration interaction approach within the envelope functionapproximation [1].p { margin-bottom: 0.25cm; direction: ltr; line-height: 115%; text-align: left; }a:link { color: rgb(0, 0, 255); }a.ctl:link { font-family: "Times New Roman"; }
