Efficient all-electron Bethe-Salpeter implementation using crystal symmetries

Jörn Stöhler, Stefan Blügel, Christoph Friedrich

We describe an all-electron implementation of the Bethe-Salpeter equation (BSE) for the calculation of optical absorption spectra in the full-potential linearized augmented-plane-w…
