Abstract
We investigate localized intragap states in mixed-valence bimetal chains in an attempt to encourage further explorations into quasi-one-dimensional halogen-bridged binuclear metal (MMX) complexes. Within a coupled electron-phonon model, soliton and polaron excitations in the two distinct ground states of MMX chains are numerically calculated and compared. Making a continuum-model analysis as well, we reveal their scaling properties with particular emphasis on the analogy between MMX chains and trans-polyacetylene.
