✦ Synopsis

Single-and two-particle states in dense plasmas differ significantly from those of ideal systems and have especially a finite lifetime. Both the bound states and the continuum edges of two-particle states are controlled by "complex single-particle energies". Furthermore, the thermodynamics can be given by these quantities. .For this reason we study the spectral weight function of the single-particle Green's function and solve the equivalent dispersion relation self-consistently in the Montroll-Ward approximation of the self energy. We give results for the continuum edges of a hydrogen plasma and of a model electron-hole plasma and discuss approximations for the equation of state.
