Momentum-resolved spectral functions of SrVO calculated by LDA+DMFT
I. A. Nekrasov, K. Held, G. Keller +6
LDA+DMFT, the merger of density functional theory in the local density approximation and dynamical mean-field theory, has been mostly employed to calculate k-integrated spectra acc…
Quantum phase transition of Ising-coupled Kondo impurities
Markus Garst, Stefan Kehrein, Thomas Pruschke +2
We investigate a model of two Kondo impurities coupled via an Ising interaction. Exploiting the mapping to a generalized single-impurity Anderson model, we establish that the model…
Explanation of the similarity of the experimental photoemission spectra of SrVO3 and CaVO3
I. A. Nekrasov, G. Keller, D. E. Kondakov +5
We present parameter-free LDA+DMFT results for the many-particle density of states of cubic SrVO3 and orthorhombic CaVO3. Both systems are found to be strongly correlated metals, b…
The LDA+DMFT Approach to Materials with Strong Electronic Correlations
K. Held, I. A. Nekrasov, G. Keller +7
LDA+DMFT is a novel computational technique for ab initio investigations of real materials with strongly correlated electrons, such as transition metals and their oxides. It combin…
Electronic properties of the three-band Hubbard model
M. B. Zoelfl, Th. Maier, Th. Pruschke +1
We study the electronic band-structure and transport properties of a CuO2-plane within the three-band Hubbard model. The Dynamical Mean-Field Theory (DMFT) is used to solve the man…
Properties of the t-J Model in the Dynamical Mean Field Theory: One-Particle Properties in the Antiferromagnetic Phase
Thomas Obermeier, Thomas Pruschke, Joachim Keller
We study the one-particle properties of the t-J model within the framework of Vollhardt's dynamical mean field theory. By introducing an AB - sublattice structure we explicitely al…
