We have been paying some attention to a state which (at zero electron-phonon couplings) is electronic in its origin (see here). Here I show how is this state proyected into the infrared and phonon coordinates. I made the simulations taking the parameters as before with the electron-Raman phonons coupling equal to zero (). We can see in the data files (unsurprisingly) that the mean Raman phonons is always zero, however the mean infrared phonons increases slightly and in a similar way as the base state. In this plot we can see that they behave in (in this respect) in a similar fashion.
So perhaps it's not too surprising to find this proyections into phonon coordinates
