Abstract
⺠We study the single-polaron properties of the one-dimensional Holstein and SSH model. ⺠The dynamical coherent potential approximation of Hartree type is used. ⺠The self-consistent Born approximation (SCBA) plus higher-order diagrams is compared. ⺠The SCBA method is only limited to the weak electron-phonon case for the both models.
