Scalable and predictive spectra of correlated molecules with moment truncated iterated perturbation theory
Oliver J. Backhouse, Alejandro Santana-Bonilla, George H. Booth
A reliable and efficient computation of the entire single-particle spectrum of correlated molecules is an outstanding challenge in the field of quantum chemistry, with standard den…

Efficient excitations and spectra within a perturbative renormalization approach
Oliver J. Backhouse, George H. Booth
We present a self-consistent approach for computing the correlated quasiparticle spectrum of charged excitations in iterative computational time. This is based o…

A wave function perspective and efficient truncation of renormalised second-order perturbation theory
Oliver J. Backhouse, Max Nusspickel, George H. Booth
We present an approach to renormalized second-order Green's function perturbation theory (GF2) which avoids all dependency on continuous variables, grids or explicit Green's functi…
