Journal ArticleDOI
First-principles calculations of the electronic structure and spectra of strongly correlated systems: the LDA+ U method
TL;DR: In this paper, a generalization of the Local Density Approximation (LDA) method for the systems with strong Coulomb correlations is presented which gives a correct description of the Mott insulators.
Journal ArticleDOI
The GW method
TL;DR: The most suitable approach up to now for studying excited-state properties of extended systems is the Green function method as discussed by the authors, which has turned out to be a fruitful approximation to the self-energy.
Journal ArticleDOI
Satellites and large doping and temperature dependence of electronic properties in hole-doped BaFe2As2
Philipp Werner,Philipp Werner,Michele Casula,Takashi Miyake,Ferdi Aryasetiawan,Ferdi Aryasetiawan,Andrew J. Millis,Silke Biermann +7 more
TL;DR: An approach to first-principles simulations that incorporates dynamically screened Coulomb interactions between iron d electrons enables the low-energy electronic structure and angle-resolved photoemission spectroscopy spectra of iron-based superconductors to be modelled with unprecedented accuracy.
Journal ArticleDOI
Multiple Plasmon Satellites in Na and Al Spectral Functions from Ab Initio Cumulant Expansion.
TL;DR: The cumulant expansion approach is used to obtain the spectral functions of Na and Al from ab initio calculations including the effects of band structure and the GW spectral functions are dramatically improved.
Journal ArticleDOI
Self-energy of ferromagnetic nickel in the GW approximation.
TL;DR: The one-electron excitation spectra of ferromagnetic nickel have been obtained from a first-principles calculation of the self-energy operator within the so-called GW approximation and a significant contribution to the spectral weight from quasiparticle peaks around that energy is found.
