A brief review of recent advances on the Mott transition: unconventional transport, spectral weight transfers, and critical behaviour
A. Georges, S. Florens, T. A. Costi
Strongly correlated metals close to the Mott transition display unusual transport regimes, together with large spectral weight transfers in optics and photoemission. We briefly rev…

Mott transition and suppression of orbital fluctuations in orthorhombic 3 perovskites
E. Pavarini, S. Biermann, A. Poteryaev +3
Using Wannier-functions, a low-energy Hamiltonian is derived for orthorhombic transition-metal oxides. Electronic correlations are treated with a new implementati…

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…
