    Abstract

    The GW plus the Bethe-Salpeter (BSE) equation approach becomes a methodology commonly used for computing the quasiparticle and optical properties of condensed-matter systems. However, GW approach requires a fine k-point sampling of the Brillouin zone, and GW plus BSE (GW-BSE) demands an even finer k-point sampling. Hence it is rather easy to reach the limits of what can be...
