Sažetak
The spectral properties of quasi-one dimensional metals at the higher energies of the order of plasmon and/or bandwidth energy are investigated by applying the standard co-called G0W0 approximation in the calculation of the dressed electron Green's function with the screened long-range three-dimensional Coulomb interaction obtained within the random phase approximation (RPA). First we assume a strictly one-dimensional electron band due to a finite transfer integral along the chains, and in the second step we extend the consideration to a more realistic case of electron band with a finite interchain hopping. As long as there is no interchain hopping the spectral function doesn't have low-energy quasi-particle, but contains broad structure with the width of the order of plasmon energy. Such spectral properties are in qualitative agreement with ARPES spectra of Bechgaard salts.
