Abstract

We investigate the ground-state properties, the far-infrared (FIR) response, and the collective modes of a square lattice of double-layered quantum dots by applying classical and quantum-mechanical concepts. Using classical self-consistent linear response theory for the dot array we derive analytic results for the magnetoabsorption spectrum and the frequencies, linewidths, and oscillator ...
