Abstract
The far-infrared absorption of triangular and square two-dimensional quantu m dots is studied by means of time simulations of the density oscillations within the time-dependent local-spin-density approximation. The absorption is spatially analyzed using a local-response theory that allows the identif ication of corner and side modes in the geometric nanostructures. The evolu tion with a vertical magnetic field of varying intensity is also discussed.
