Abstract
length scale comparable with the extension of the relevant quantum states. A general formulation,including Coulomb correlation, is derived within the density-matrix formalism and applied to theprototypical case of coupled quantum wires. The results show that excitonic effects may have acrucial impact on the local absorption, with implications for the spatial resolution and the interpretationof near-field optical spectra
