- The authors give a critical discussion of different current band structure schemes and their relaxation to experiment. They then discuss the connections, exact and approximate, that exist between the electron self-energy and experiment, considering in particular optical absorption and photoemission. Different computationally feasible approximation schemes based on a dynamic generalization of the nonlocal Hartree-Fock exchange potential are considered.
