Abstract
We present a detailed calculation of the electronic structure of SrVO based on the +DMFT method. We show that a proper inclusion of the frequency-dependent Hubbard and the nonlocal self-energy via the 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. The +DMFT results for SrVO are not attainable within the approximation or the LDA+DMFT scheme. We also compare the results of +DMFT to DMFT calculations based on the quasiparticle bands.
