The Role of hybridization in NaxCoO2 and the Effect of Hydration
C. A. Marianetti, G. Kotliar, G. Ceder
Density functional theory (DFT) within the local density approximation (LDA) is used to understand the electronic properties of Na1/3CoO2 and Na1/3CoO2(H2O)4/3, which was recently…
Many-Body Approximation Scheme Beyond GW
Ping Sun, Gabriel Kotliar
We explore the combination of the extended dynamical mean field theory (EDMFT) with the GW approximation (GWA); the former sums the local contributions to the self-energies to infi…
Dynamical correlations in multiorbital Hubbard models: Fluctuation-exchange approximations
V. Drchal, V. Janis, J. Kudrnovsky +4
We study the two band degenerate Hubbard model using the Fluctuation Exchange approximation (FLEX) method and compare the results with Quantum Monte-Carlo calculations. Both the se…
Temperature dependent transport of correlated disordered electrons: elastic vs. inelastic scattering
M. C. O. Aguiar, E. Miranda, V. Dobrosavljevic +2
Temperature dependent transport of disordered electronic systems is examined in the presence of strong correlations. In contrast to what is assumed in Fermi liquid approaches, fini…
Non-Fermi liquid behavior from two-dimensional antiferromagnetic fluctuations: a renormalization-group and large-N analysis
Sergey Pankov, Serge Florens, Antoine Georges +2
We analyze the Hertz-Moriya-Millis theory of an antiferromagnetic quantum critical point, in the marginal case of two dimensions (d=2,z=2). Up to next-to-leading order in the numbe…
