Polaron Mass and Electron-Phonon Correlations in the Holstein Model
Figure 2
Ratio of the Modified Lang-Firsov polaron mass to the bare band mass versus e-ph coupling in (a) 1D, (b) 2D, and (c) 3D. A set of twelve values ranging from the antiadiabatic to the adiabatic regime is considered. From left to right: . meV. The diamonds mark the occurrence of the self-trapping event.
