For strong electron-phonon coupling, it is sometimes advantageous to add more phonon basis states very near to the electron, called a “tower.” Even with a tower, convergence is slower at strong coupling, corresponding to a shallower slope in Fig. 22

All presented el-ph correlation functions are evaluated for wave functions that are normalized to one electron per site. For conventional normalization, there would be an additional (formula presented) factor, where N is the number of sites in the system

the weak-coupling regime, the extent of the el-ph correlations at (formula presented) is much larger than at (formula presented). For the 1D polaron, the el-ph correlations decay exponentially at all k for all parameters; the polaron and additional phonon are bound at (formula presented). It is not clear that this is the case in three dimensions

A comparison of energies obtained by a wider variety of methods is contained in Ref. 17. Note that what is referred to as the “Toyozawa variation” in that reference is a more sophisticated trial function than what we call the Toyozawa wave function [Eq. (8)]
