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…
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…
Dimensional crossover and deconfinement in Bechgaard salts
T. Giamarchi, S. Biermann, A. Georges +1
The Bechgaard salts are made of weakly coupled one dimensional chains. This particular structure gives the possibility to observe in these systems a dimensional crossover between a…
