Spectral density functional approach to electronic correlations and magnetism in crystals
A. I. Lichtenstein, M. I. Katsnelson, G. Kotliar
A novel approach to electronic correlations and magnetism of crystals based on realistic electronic structure calculations is reviewed. In its simplest form it is a combination of…
Correlation Effects on Magnetic Anisotropy in Fe and Ni
I. Yang, S. Y. Savrasov, G. Kotliar
We calculate magnetic anisotropy energy of Fe and Ni by taking into account the effects of strong electronic correlations, spin-orbit coupling, and non-collinearity of intra-atomic…
Calculations of Optical Properties in Strongly Correlated Materials
V. S. Oudovenko, G. Palsson, K. Haule +2
We present a new method to calculate optical properties of strongly correlated systems. It is based on dynamical mean field theory and it uses as an input realistic electronic stru…
Dynamical Mean Field Theory, Model Hamiltonians and First Principles Electronic Structure Calculations
G. Kotliar, S. Y. Savrasov
We review the basic ideas of the dynamical mean field theory (DMFT) and some of the insights into the electronic structure of strongly correlated electrons obtained by this method…
Cellular Dynamical Mean Field Theory for the 1D Extended Hubbard Model
C. J. Bolech, S. S. Kancharla, G. Kotliar
We explore the use of exact diagonalization methods for solving the self consistent equations of the cellular dynamical mean field theory (CDMFT) for the one dimensional regular an…
