Optical control of exciton and spin states in a quantum dot by excitation with twisted light

We discuss how the excitation of a quantum dot can benefit from the special properties of twisted light beams. First we address the question of the appropriate theoretical description of the light-matter coupling in this system, i.e., of the most appropriate gauge. Then we discuss the optical transi...
