Lorke et al., Phys. Rev. Lett. (to be published)]. The overall agreement between theory and experiment is fairly good, which on the one hand confirms that the experimental peaks indeed reflect the ringlike structure of the sample, and on the other hand, asseses the suitability of the theoretical method to describe such nanostructures. The addition energies of one- and two-electron rings are also reported and compared with the corresponding capacitance spectra Nanoestructures Semiconductors Espectre infraroig Nanostructures Semiconductors Vibrational spectra Far-infrared spectroscopy of nanoscopic InAs rings
