Anomalous dispersion of optical phonons at the neutral-ionic transition: Evidence from diffuse X-ray scattering
Gabriele D'Avino, Alberto Girlando, Anna Painelli +2
Diffuse X-ray data for mixed stack organic charge-transfer crystals approaching the neutral-ionic phase transition can be quantitatively explained as due to the softening of the op…
Dielectric response of modified Hubbard models with neutral-ionic and Peierls transitions
Zoltan G. Soos, Sharon A. Bewick, Andrea Peri +1
The dipole P(F) of systems with periodic boundary conditions (PBC) in a static electric field F is applied to one-dimensional Peierls-Hubbard models for organic charge-transfer (CT…
Charge fluctuations and electron-phonon coupling in organic charge-transfer salts with neutral-ionic and Peierls transitions
A. Girlando, A. Painelli, S. A. Bewick +1
The first-order transition of the charge-transfer complex TTF-CA (tetrathiafulvalene-chloranil) is both a neutral-ionic and a Peierls transition. In related organic charge transfer…
