Tensor-network study of the extended Hubbard model shows an analytical DH-pair formula predicts energy increase rates well but requires exciton energy as effective gap when V induces excitons.
This implies that the DH pair count (ND) satisfies ND ∝ 1 − exp(− Γt), and should rise lin- early for small Γ t
