Abstract

We review recent far-infrared transmission experiments on modulation-doped quantum dots, quantum wires and antidot arrays with tailored potentials. In contrast to the simple two-mode behavior that is observed, in a magnetic field, in many experiments on dots with a parabolic potential, a tailored nonparabolic potential breaks the Kohns theorem and allows one to observe detailed many-body effects from internal electron motion in the lateral quantum structures. Among these are high-frequency magnetoplasmon modes which show interesting anticrossing behaviors, below-Kohn modes and anticyclotron motion in antidot arrays.
