    "abstract": "Exciton effects on conjugated polymers are investigated in soliton lattice\nstates. We use the Su-Schrieffer-Heeger model with long-range Coulomb\ninteractions. The Hartree-Fock (HF) approximation and the single-excitation\nconfiguration- interaction (single-CI) method are used to obtain optical\nabsorption spectra. The third-harmonic generation (THG) at off-resonant\nfrequencies is calculated as functions of the soliton concentration and the\nchain length of the polymer. The magnitude of the THG at the 10 percent doping\nincreases by the factor about 10^2 from that of the neutral system. This is\nowing to the accumulation of the oscillator strengths at the lowest exciton\nwith increasing the soliton concentration. The increase by the order two is\ncommon for several choices of Coulomb interaction strengths.",
