Quantitative Determination of Temperature in the Approach to Magnetic Order of Ultracold Fermions in an Optical Lattice
Robert Jördens, Leticia Tarruell, Daniel Greif +12
We perform a quantitative simulation of the repulsive Fermi-Hubbard model using an ultracold gas trapped in an optical lattice. The entropy of the system is determined by comparing…
Local moment versus Kondo behavior of the 4f-electrons in rare-earth iron oxypnictides
L. Pourovskii, V. Vildosola, S. Biermann +1
We consider the role played by the 4f states in the rare-earth oxyarsenides REOFeAs (RE=Ce,Pr,Nd) and the oxyphosphate CeOFeP, using a first-principles technique that combines the…
Evolution of the gaps through the cuprate phase-diagram
W. Guyard, M. Le Tacon, M. Cazayous +4
The actual physical origin of the gap at the antinodes, and a clear identification of the superconducting gap are fundamental open issues in the physics of high- superconducto…
Self-consistency over the charge-density in dynamical mean-field theory: a linear muffin-tin implementation and some physical implications
L. V. Pourovskii, B. Amadon, S. Biermann +1
We present a simple implementation of the dynamical mean-field theory approach to the electronic structure of strongly correlated materials. This implementation achieves full self-…
Interaction-induced adiabatic cooling and antiferromagnetism of cold fermions in optical lattices
F. Werner, O. Parcollet, A. Georges +1
We propose an interaction-induced cooling mechanism for two-component cold fermions in an optical lattice. It is based on an increase of the ``spin'' entropy upon localisation, an…
The alpha-gamma transition of Cerium is entropy-driven
B. Amadon, S. Biermann, A. Georges +1
We emphasize, on the basis of experimental data and theoretical calculations, that the entropic stabilization of the gamma-phase is the main driving force of the alpha-gamma transi…
