text: Many-body perturbation theory is a well-established ab initio electronic-structure
method based on Green functions. Although computationally more demanding than
density functional theory, it has the distinct advantage that the exact expressions
for all relevant observables, including the ground-state total energy, in terms
of the Green function are known explicitly. The most important application, however,
lies in the calculation of excited states, whose energies correspond directly
to the poles of the Green function in the complex frequency plane. The accuracy
of results obtained within this framework is only limited by the choice of the
exchange-correlation self-energy, which must still be approximated in actual implementations.
In this respect, the GW approximation has proved highly successful for systems
governed by the Coulomb interaction. It yields band structures of solids, including
the band gaps of semiconductors, as well as atomic and molecular ionization energies
in very good quantitative agreement with experimental photoemission data.
