Far infrared giant dipole resonances in neutral quantum dots
Abstract
A resonance behaviour of the far infrared absorption probability at a frequency N1/4 is predicted for clusters of N electron-hole pairs (2 N 110) confined in disk-shaped quantum dots. For radially symmetric dots, the absorption is dominated by a Giant Dipole Resonance, which accounts for more than 98 % of the energy-weighted photoabsorption sum rule.
