Second-order quasiparticle electron propagator

Quasiparticle Second order Dilated Electron Propagator /42/ 124.98 0.05... [Pg.264]

The proposals found here can be seen as the result of a two-way strategy for the treatment of large molecules. First, we improve on the accuracy of the very efficient second order approximation. In addition, we introduce approximations that lower considerably the required computer resources for the use of higher-order approximations to the electron propagator within the quasiparticle approach. [Pg.7]
