HIGHLIGHTS
- who: Static and collaborators from the Laboratoire de Chimie et Physique Quantiques (UMR, ), Universitu00e9 de Toulouse, CNRS, UPS, Toulouse, France have published the research work: Static and dynamic Bethe-Salpeter equations in the T-matrix approximation, in the Journal: (JOURNAL)
- what: The authors focus on neutral excitations and the authors explore how the T-matrix approximation performs within the Bethe- Salpeter equation (BSE) of many-body perturbation theory .
SUMMARY
The GW approximation1 of many-body perturbation theory2 is becoming a method of choice to target charged excitations (i.e., ionization potentials . . .
