Kinks in the dispersion of strongly correlated electrons
K. Byczuk, M. Kollar, K. Held +4
The properties of condensed matter are determined by single-particle and collective excitations and their interactions. These quantum-mechanical excitations are characterized by an…
Comparative study of correlation effects in CaVO3 and SrVO3
I. A. Nekrasov, G. Keller, D. E. Kondakov +5
We present parameter-free LDA+DMFT (local density approximation + dynamical mean field theory) results for the many-body spectra of cubic SrVO3 and orthorhombic CaVO3. Both systems…
Two Aspects of the Mott-Hubbard Transition in Cr-doped V_2O_3
K. Held, J. W. Allen, V. I. Anisimov +5
The combination of bandstructure theory in the local density approximation with dynamical mean field theory was recently successfully applied to VO -- a material which unde…
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…
Mutual Experimental and Theoretical Validation of Bulk Photoemission Spectra of Sr1-xCaxVO3
A. Sekiyama, H. Fujiwara, S. Imada +14
We report high-resolution high-energy photoemission spectra together with parameter-free LDA+DMFT (local density approximation + dynamical mean-field theory) results for Sr1-xCaxVO…
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…
