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…
Charge dynamics in strongly correlated one-dimensional Cu-O chain systems revealed by inelastic X-ray scattering
S. Suga, S. Imada, A. Higashiya +11
We report on the Cu 1s resonant inelastic X-ray scattering (RIXS) of Cu-O one-dimensional (1D) strongly correlated insulator systems with contrasting atomic arrangements, namely ed…
Filling of the Mott-Hubbard gap in the high temperature photoemission spectrum of (V_0.972Cr_0.028)_2O_3
S. -K. Mo, H. -D. Kim, J. W. Allen +8
Photoemission spectra of the paramagnetic insulating (PI) phase of (V_0.972Cr_0.028)_2O_3, taken in ultra high vacuum up to the unusually high temperature (T) of 800 K, reveal a pr…
Prominent quasi-particle peak in the photoemission spectrum of the metallic phase of V_2O_3
S. -K. Mo, J. D. Denlinger, H. -D. Kim +14
We present the first observation of a prominent quasi-particle peak in the photoemission spectrum of the metallic phase of V_2O_3 and report new spectral calculations that combine…
