Electronic structure of SrVO 3 within G W +DMFT

We present a detailed calculation of the electronic structure of SrVO${}_{3}$ based on the $GW$+DMFT method. We show that a proper inclusion of the frequency-dependent Hubbard $U$ and the nonlocal self-energy via the $GW$ approximation, as well as a careful treatment of the Fermi level, are crucial for obtaining an accurate and coherent picture of the quasiparticle band structure and satellite features of SrVO${}_{3}$. The $GW$+DMFT results for SrVO${}_{3}$ are not attainable within the $GW$ approximation or the LDA+DMFT scheme. We also compare the results of $GW$+DMFT to DMFT calculations based on the $GW$ quasiparticle bands.
