Excitons in soliton and bipolaron lattice states of doped Peierls systems

Kikuo Harigaya, Yukihiro Shimoi, Shuji Abe

Exciton effects on soliton and bipolaron lattice states are investigated using an electron-lattice Peierls model with long-range Coulomb interactions. The Hartree-Fock (HF) approxi…
