Abstract

We study a nonuniversal contribution to the dephasing rate of conduction electrons due to local vibrational modes. The inelastic-scattering rate is strongly influenced by multiphonon excitations, exhibiting oscillatory behavior. For higher frequencies, it saturates to a finite, coupling dependent value. In the strong-coupling limit, the phonon is almost completely softened and the inelastic cross section reaches its maximal value. This represents a magnetic-field insensitive contribution to the dephasing time in mesoscopic systems, in addition to magnetic impurities.
