Sum-rules for Raman scattering off strongly correlated electron systems
L. de' Medici, A. Georges, G. Kotliar
We investigate sum-rules applying to the Raman intensity in a strongly correlated system close to the Mott transition. Quite generally, it can be shown that, provided the frequency…
Effect of Crystal-Field Splitting and Inter-Band Hybridization on the Metal-Insulator Transitions of Strongly Correlated Systems
Alexander I. Poteryaev, Michel Ferrero, Antoine Georges +1
We investigate a quarter-filled two-band Hubbard model involving a crystal-field splitting, which lifts the orbital degeneracy as well as an inter-orbital hopping (inter-band hybri…
Nodal/Antinodal Dichotomy and the Two Gaps of a Superconducting Doped Mott Insulator
M. Civelli, M. Capone, A. Georges +4
We study the superconducting state of the hole-doped two-dimensional Hubbard model using Cellular Dynamical Mean Field Theory, with the Lanczos method as impurity solver. In the un…
Condensed Matter Physics With Light And Atoms: Strongly Correlated Cold Fermions in Optical Lattices
Antoine Georges
Various topics at the interface between condensed matter physics and the physics of ultra-cold fermionic atoms in optical lattices are discussed. The lectures start with basic cons…
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…
