Magneto-optics of arrays of quantum dots and antidots

We study the optical absorption of arrays of quantum dots and antidots in a perpendicular homogeneous magnetic field. The electronic system is described quantum mechanically using a Hartree approximation for the mutual Coulomb interaction of the electrons. The model is particularly suited for the investigation of the far-infrared absorption of gate-modulated systems, where the gate not only controls the distribution of the electrons, but also modulates the external radiation field.
