Collective excitations in semiconductor superlattices are studied beyond the randomphase approximation (RPA). The Singwi, 'Tosi, Land and SjΓΆlander (STLS) theory, which accounts for exchange and short-range correlations effects through an effective potential depending on the structure factor, is gen
We apply the dielectric formalism within random phase approximation (RPA) and G 0 W 0 approximation to the tight-binding multi-band systems with the three-dimensional long-range Coulomb interaction in order to calculate the one-particle spectral function for TTF-TCNQ, and to investigate dielectric p
