Ab Initio Bethe-Salpeter Equation Approach to Neutral Excitations in Molecules with Numeric Atom-Centered Orbitals
Chi Liu, Jan Kloppenburg, Xinguo Ren +3
The Bethe-Salpeter equation (BSE) based on GW quasiparticle levels is a successful approach for calculating the optical gaps and spectra of solids and also for predicting the neutr…

Comparing particle-particle and particle-hole channels of random-phase approximation
Muhammad N. Tahir, Xinguo Ren
We present a comparative study of particle-hole and particle-particle channels of random-phase approximation (RPA) for molecular dissociations of different bonding types. We introd…
