Static vs. dynamical mean field theory of Mott antiferromagnets
G. Sangiovanni, A. Toschi, E. Koch +11
Studying the antiferromagnetic phase of the Hubbard model by dynamical mean field theory, we observe striking differences with static (Hartree-Fock) mean field: The Slater band is…
Energetic balance of the superconducting transition across the BCS-Bose E instein crossover in the attractive Hubbard model
A. Toschi, M. Capone, C. Castellani
We investigate by means of Dynamical Mean-Field Theory the crossover from BCS superconductivity to Bose-Einstein (BE) condensation of preformed pairs in the attractive Hubbard mode…
Temperature dependence of the optical spectral weight in the cuprates: Role of electron correlations
A. Toschi, M. Capone, M. Ortolani +3
We compare calculations based on the Dynamical Mean-Field Theory of the Hubbard model with the infrared spectral weight of LaSrCuO and other cuprates. With…
Quasi-particle dephasing time in disordered d-wave superconductors
M. Bruno, A. Toschi, L. Dell'Anna +1
We evaluate the low-temperature cutoff for quantum interference 1/tf induced in a d-wave superconductor by the diffusion enhanced quasiparticle interactions in the presence of diso…
