Towards realistic electronic structure calculations of strongly correlated electron systems
V. S. Oudovenko, G. Palsson, K. Haule +2
We review some aspects of the realistic implementation of the dynamical mean-field method. We extend the techniques introduced in Ref.[A. Georges, G. Kotliar, W. Krauth, and M.J. R…
Interpolative Approach for Solving Quantum Impurity Model Based on the Slave--Boson Mean--Field Approximation
V. Oudovenko, K. Haule, S. Y. Savrasov +2
A rational representation for the self-energy is explored to interpolate the solution of the Anderson impurity model in general orbitally degenerate case. Several constrains such a…
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…
Density response of the t-J model and renormalization of breathing and half-breathing phonon modes: A slave-fermion calculation
P. Horsch, G. Khaliullin, V. Oudovenko
The density fluctuation spectrum is calculated for the t-J model in the low-doping regime using a slave-fermion method for the constrained fermions. The obtained res…
Normal and superconducting state in the presence of forward electron-phonon and impurity scattering
O. V. Danylenko, O. V. Dolgov, M. L. Kulic +1
Impurities with the pronounced forward scattering (FS impurities) change analytical properties of the quasiparticle Green's function substantially compared to the isotropic scatter…
