Faddeev random phase approximation for molecules

Author

Abstract
The many body Green's function is an adequate tool to study the groundstate energy and ionization energies of molecules. The Faddeev Random Phase Approximation (FRPA)[1] makes use of Faddeev equations to couple two-particle - one-hole (2p1h) and two-hole - one-particle (2h1p) excitations to the single-particle spectrum. Solving these equations implies an inite partial summation of the perturbation expansion of the self-energy. This method goes beyond the ADC(3)[2] approximation by treating both the particle-hole and particle-particle interactions at the RPA level. We present the results of our calculations for some diatomic molecules.
