Franck-Condon Factors as Spectral Probes of Polaron Structure
David W. Brown, Aldo H. Romero, Katja Lindenberg
We apply the Merrifield variational method to the Holstein molecular crystal model in D dimensions to compute non-adiabatic polaron band energies and Franck-Condon factors at gener…
Electron-Phonon Correlations, Polaron Size, and the Nature of the Self-Trapping Transition
A. H. Romero, David W. Brown, Katja Lindenberg
We analyze electron-phonon correlation functions measured in 1D polaron ground states of the Holstein Hamiltonian using the Global-Local variational method. The spatial collapse of…
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…
