Some clarifications on cond-mat/0508763 by M. I. Katsnelson
M. Feldbacher, R. Arita, K. Held +1
Katsnelson submitted his Comment on our paper "Projective Quantum Monte Carlo Method for the Anderson Impurity Model and its Application to Dynamical Mean Field Theory" to Phys. Re…
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…
Nonequilibrium transport through parallel double quantum dots in the Kondo regime
Y. -F. Yang, K. Held
We extend a perturbative, nonequilibrium renormalization group approach to multi-orbital systems and apply it for studying transport through two parallel quantum dots coupled elect…
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…
Metallic Ferromagnetism - an Electronic Correlation Phenomenon
D. Vollhardt, N. Blümer, K. Held +1
New insights into the microscopic origin of itinerant ferromagnetism were recently gained from investigations of electronic lattice models within dynamical mean-field theory (DMFT)…
