Effects of dimensionality and anisotropy on the Holstein polaron
Aldo H. Romero, David W. Brown, Katja Lindenberg
We apply weak-coupling perturbation theory and strong-coupling perturbation theory to the Holstein molecular crystal model in order to elucidate the effects of anisotropy on polaro…
The breakdown of adiabatic polaron theory in one, two, and three dimensions and the reformation of the large polaron concept
Aldo H. Romero, David W. Brown, Katja Lindenberg
We prove variationally that at weak coupling in one, two, and three dimensions there exist correlated electron-phonon states below the approximate ground states characteristically…
Polaron Effective Mass, Band Distortion, and Self-Trapping in the Holstein Molecular Crystal Model
Aldo H. Romero, David W. Brown, Katja Lindenberg
We present polaron effective masses and selected polaron band structures of the Holstein molecular crystal model in 1-D as computed by the Global-Local variational method over a wi…
Exact weak-coupling radius of the Holstein polaron in one, two, and three dimensions
Aldo H. Romero, David W. Brown, Katja Lindenberg
We apply weak-coupling perturbation theory to the Holstein molecular crystal model in order to compute an electron-phonon correlation function characterizing the shape and size of…
