Ab Initio Linear and Pump-Probe Spectroscopy of Excitons in Molecular Crystals
Alan M. Lewis, Timothy C. Berkelbach
Linear and non-linear spectroscopies are powerful tools used to investigate the energetics and dynamics of electronic excited states of both molecules and crystals. While highly ac…

Vertex corrections to the polarizability do not improve the GW approximation for the ionization potential of molecules
Alan M. Lewis, Timothy C. Berkelbach
The approximation is based on the neglect of vertex corrections, which appear in the exact self-energy and the exact polarizability. Here, we investigate the importance of ver…
