| Abstract: | The frequency dependent conductivity of added charge (e.g. solitons) to a dimerized Peieres condensate with N coupled phonons is studied. The electron-Phonon system, with electron -electron interactions and pinning effects, yields in the adiabatic and continuum limits an infrared absprption whose structure is independent of the charge configuration. The kinetic mass of the charge affects only the pinning parameter and the over-all magnitude of the absorption. This mass is es timated from experimental data and compared with theoretical soliton and polaron masses. |
