    "abstract": "A basic concept to calculate physical features of non-ideal plasmas, such as\noptical properties, is the spectral function which is linked to the\nself-energy. We calculate the spectral function for a non-relativistic hydrogen\nplasma in $GW$-approximation. In order to go beyond $GW$ approximation, we\ninclude self-energy and vertex correction to the polarization function in\nlowest order. Partial compensation is observed. The relation of our approach to\n$GW$ and $GW\\Gamma$ calculations in other fields, such as the band-structure\ncalculations in semiconductor physics, is discussed. From the spectral function\nwe derive the absorption coefficient due to inverse bremsstrahlung via the\npolarization function. As a result, a significant reduction of the absorption\nas compared to the Bethe-Heitler formula for bremsstrahlung is obtained.",
