Kinks in the dispersion of strongly correlated electrons
K. Byczuk, M. Kollar, K. Held +4
The properties of condensed matter are determined by single-particle and collective excitations and their interactions. These quantum-mechanical excitations are characterized by an…
Pseudogaps in Strongly Correlated Metals: Optical Conductivity within the Generalized Dynamical Mean-Field Theory Approach
E. Z. Kuchinskii, I. A. Nekrasov, M. V. Sadovskii
Optical conductivity of the weakly doped two-dimensional repulsive Hubbard model on the square lattice with nearest and next nearest hoppings is calculated within the generalized d…
Pseudogap behaviour in Bi2212: Results of Generalized DMFT Approach
E. Z. Kuchinskii, I. A. Nekrasov, Z. V. Pchelkina +1
To describe pseudogap regime in Bi2212 we employ novel generalized ab initio LDA+DMFT+Sigma_k hybrid scheme. This scheme is based on the strategy of one of the most powerfull compu…
LDA+DMFT computation of the electronic spectrum of NiO
X. Ren, I. Leonov, G. Keller +3
The electronic spectrum, energy gap and local magnetic moment of paramagnetic NiO are computed by using the local density approximation plus dynamical mean-field theory (LDA+DMFT).…
Evidence for strong electronic correlations in the spectra of SrRuO
Z. V. Pchelkina, I. A. Nekrasov, Th. Pruschke +4
The importance of electronic correlation effects in the layered perovskite SrRuO is evidenced. To this end we use state-of-the-art LDA+DMFT (Local Density Approximation + D…
Electronic structure, magnetic and optical properties of intermetallic compounds R2Fe17 (R=Pr,Gd)
Yu. V. Knyazev, A. V. Lukoyanov, Yu. I. Kuz'min +2
In this paper we report comprehensive experimental and theoretical investigation of magnetic and electronic properties of the intermetallic compounds Pr2Fe17 and Gd2Fe17. For the f…
