Direct evidence of overdamped Peierls-coupled modes in TTF-CA temperature-induced phase transition
A. Girlando, M. Masino, A. Painelli +5
In this paper we elucidate the optical response resulting from the interplay of charge distribution (ionicity) and Peierls instability (dimerization) in the neutral-ionic, ferroele…
Lattice dynamics and electron-phonon coupling in β-(BEDT-TTF)_2I_3 organic superconductor
A. Girlando, M. Masino, G. Visentini +3
The crystal structure and lattice phonons of (BEDT-TTF)_2I_3 superconducting β-phase are computed and analyzed by the Quasi Harmonic Lattice Dynamics (QHLD) method. Whereas the cry…
The Dimer Model for k-phase Organic Superconductors
G. Visentini, A. Painelli, A. Girlando +1
We prove that the upper electronic bands of k-phase BEDT-TTF salts are adequately modeled by an half-filled tight-binding lattice with one site per cell. The band parameters are de…
Exact numerical diagonalization of one-dimensional interacting electrons nonadiabatically coupled to phonons
G. P. Borghi, A. Girlando, A. Painelli +1
We study the role of non-adiabatic Holstein electron-phonon coupling on the neutral-ionic phase transition of charge transfer crystals which can be tuned from continuous to discont…
