All-electron quasi-particle self-consistent $G W$ band structures for SrTiO $_{3}$ including lattice polarization corrections in different phase

Churna Bhandari, Mark van Schilfgaarde, Takao Kotani +1

The electronic band structure of SrTiO $_{3}$ is investigated in the all-electron QS $G W$ approximation. Unlike previous pseudopotential based QS $G W$ or single-shot $G_{0} W_{0}$ calculatio…
