Ab Initio Lifetime and Concomitant Double-Excitation Character of Plasmons at Metallic Densities
Alan M. Lewis, Timothy C. Berkelbach
The accurate calculation of excited state properties of interacting electrons in the condensed phase is an immense challenge in computational physics. Here, we use state-of-the-art…
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…
On the low magnetic field effect in radical pair reactions
Alan M. Lewis, Thomas P. Fay, David E. Manolopoulos +3
Radical pair recombination reactions are known to be sensitive to the application of both low and high magnetic fields. The application of a weak magnetic field reduces the singlet…
