(color online) Schematic picture of Fock space for electron–phonon states. The intersections of horizontal and vertical lines indicate the electronic sites and the corresponding phononic states. The solid lines refer to electronic hopping terms and the vertical and diagonal dashed lines are used to represent the local and nonlocal e–ph interactions, respectively.
