Abstract

Binding energies and linear optical properties of quasi-one-dimensional excitons in a quantum wire in strong magnetic fields are predicted. It is shown that magnetoexcitons confined in a quantum-well wire possess a hydrogenic spectrum with bound states and a continuum of scattering states, in contrast to two-dimensional magnetoexcitons that are always bound. The appearance and shape of Fano resonances in the optical spectra are explained and the influence of the Coulomb interaction on the optical spectra is discussed both analytically and numerically.
