Abstract
The effect of interchain interaction on the nonlinear excitations in the one-dimensional (1-D) Peierls-Hubbard system is investigated by the photo-induced absorption (PA) measurements of the halogen-bridged metal complexes (the MX compounds; M=Pt and X=Br or I), changing the strength of the interchain coupling via the hydrogen-bonds between the charge-density wave (CDW) states. Systematic analysis of the PA signals provides a clear evidence for photogeneration of solitons and polarons which have been theoretically predicted. From the excitation profile of the PA signals, informations are obtained useful for general understanding of the relaxation processes of photo-excited states and the excitonic effect in the 1-D CDW state.Keywords
