Core-hole induced misalignment between Van-Hove singularities and K-edge fine structure in carbon nanotubes
Martin Unzog, Alexey Tal, Pedro Melo +4
We investigate the relationship between the K-edge fine structure of isolated single-wall carbon nanotubes (SWCNTs) and the Van Hove singularities (VHSs) in the conduction band den…

Core-hole excitations using the projector augmented-wave method and the Bethe-Salpeter equation
Martin Unzog, Alexey Tal, Georg Kresse
We present an implementation of the Bethe-Salpeter equation (BSE) for core-conduction band pairs within the framework of the projector augmented-wave method. For validation, the me…
