Abstract
It is shown that a quadratic electron-phonon interaction leads. under certain conditions, to temperature-dependent band narrowing and an inverse lifetime quadratic in the phonon occupation numbers. These explain the prominent metallic properties of organic metals of the TTF-TCNQ family. in particular the enhancement of the magnetic susceptibility.
