Abstract :
The effect of quantum fluctuation on the CDW state of the MX chain complex is studied with the Green Function method, which can deal with any phonon frequency and infinite chain. It is shown that the effect is dependent on the electron-phonon coupling. For strong coupling, the CDW amplitude is only slightly reduced; but for weak coupling, the reduction becomes so serious that the CDW is almost destroyed.
