Polaronic features in the Su-Schrieffer-Heeger model
Creators
Description
A diagrammatic perturbative study of (i) effective mass and (ii) electron spectral function versus the adiabatic parameter in the Su-Schrieffer-Heeger model is presented. When zone boundary phonons energetically compete with band electrons we observe a sizeable mass enhancement. In two dimensions, a spread of the spectral weight signals the onset of polaron formation
