Orbital selective Mott transition in multi-band systems: slave-spin representation and dynamical mean-field theory
L. de' Medici, A. Georges, S. Biermann
We examine whether the Mott transition of a half-filled, two-orbital Hubbard model with unequal bandwidths occurs simultaneously for both bands or whether it is a two-stage process…
Is the Mott transition relevant to f-electron metals ?
L. de' Medici, A. Georges, G. Kotliar +1
We study how a finite hybridization between a narrow correlated band and a wide conduction band affects the Mott transition. At zero temperature, the hybridization is found to be a…
Quantum critical properties of the Bose-Fermi Kondo Model in a large-N limit
Lijun Zhu, Stefan Kirchner, Qimiao Si +1
Studies of non-Fermi liquid properties in heavy fermions have led to the current interest in the Bose-Fermi Kondo model. Here we use a dynamical large-N approach to analyze an SU(N…
Electronic Structure of Strongly Correlated Materials: towards a First Principles Scheme
Silke Biermann, Ferdi Aryasetiawan, Antoine Georges
We review a recent proposal of a first principles approach to the electronic structure of materials with strong electronic correlations. The scheme combines the GW method with dyna…
A First Principles Scheme for Calculating the Electronic Structure of Strongly Correlated Materials: GW+DMFT
Ferdi Aryasetiawan, Silke Biermann, Antoine Georges
We give a detailed description of a recently proposed first principles approach to the electronic structure of strongly correlated materials. The method combines the GW approximati…
The Local Impurity Self Consistent Approximation (LISA) to Strongly Correlated Fermion Systems and the Limit of Infinite Dimensions
A. Georges, G. Kotliar, W. Krauth +1
We review the dynamical mean-field theory of strongly correlated fermion systems which is based on a mapping of lattice models onto quantum impurity models subject to a self-consis…
