Soliton-induced optical absorption of halogen-bridged mixed-valence binuclear metal complexes
arXiv:cond-mat/0407056 · doi:10.1103/PhysRevB.70.115112
Abstract
Employing the one-dimensional single-band extended Peierls-Hubbard model, we investigate optical conductivity for solitonic excitations in halogen-bridged binuclear metal (MMX) complexes. Photoinduced soliton absorption spectra for MMX chains possibly split into two bands, forming a striking contrast to those for conventional mononuclear metal (MX) analogs, due to the broken electron-hole symmetry combined with relevant Coulomb and/or electron-phonon interactions.
