Non-Drude universal scaling laws for the optical response of local Fermi liquids
Christophe Berthod, Jernej Mravlje, Xiaoyu Deng +3
We investigate the frequency and temperature dependence of the low-energy electron dynamics in a Landau Fermi liquid with a local self-energy. We show that the frequency and temper…
How bad metals turn good: spectroscopic signatures of resilient quasiparticles
Xiaoyu Deng, Jernej Mravlje, Rok Zitko +3
We investigate transport in strongly correlated metals. Within dynamical mean-field theory, we calculate the resistivity, thermopower, optical conductivity and thermodynamic proper…
Strong electronic correlations from Hund's coupling
Antoine Georges, Luca de' Medici, Jernej Mravlje
Strong electronic correlations are often associated with the proximity of a Mott insulating state. In recent years however, it has become increasingly clear that the Hund's rule co…
Exploring the Dark Side of Cuprate Superconductors: s-wave Symmetry of the Pseudogap
S. Sakai, S. Blanc, M. Civelli +12
We reveal the full energy-momentum structure of the pseudogap of underdoped high-Tc cuprate superconductors. Our combined theoretical and experimental analysis explains the spectra…
Mott transition of fermionic mixtures with mass imbalance in optical lattices
T. -L. Dao, M. Ferrero, P. S. Cornaglia +1
We investigate the effect of mass imbalance in binary Fermi mixtures loaded in optical lattices. Using dynamical mean-field theory, we study the transition from a fluid to a Mott i…
