    Competition between Energy-Dependent U and Nonlocal Self-Energy in Correlated Materials: Application of GW+DMFT to SrVO3

    Sakuma, R. ; Werner, Philipp ; Aryasetiawan, F.

    In: Proceedings of Computational Science Workshop 2014 (CSW2014), 2015, vol. 5, p. -

    We describe an implementation of the GW+DMFT method and apply it to calculate the electronic structure of SrVO₃. Our results show that there is a strong competition between the frequency-dependent Hubbard U and the non-local self-energy via the GW approximation. It is crucial to take into account these two aspects in order to obtain an accurate and coherent picture of the...

    Electronic structure of SrVO3 within GW+DMFT

    Sakuma, R. ; Werner, Philipp ; Aryasetiawan, F.

    In: Physical Review B, 2013, vol. 88, no. 23, p. 235110

    We present a detailed calculation of the electronic structure of SrVO3 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...
