Electron-vibrational model for an organic dimer based on cation radicals TTF+ and anion radicals TCNQ−

The electron-vibrational model for an organic dimer proposed in this paper allows one to take into account not only the electron correlation (the organic charge transfer complexes are strongly correlated systems) through the dimerized Hubbard model but also the internal structure of the dimer and each of its monomers by introducing an additional term into the Hamiltonian to describe the interaction between the electrons and the vibrational subsystem. Thus, it provides ample opportunities to minutely describe the polarization and conduction properties of organic dimer systems.
