Quantum criticality in the two-dimensional periodic Anderson model
T. Schäfer, A. A. Katanin, M. Kitatani +2
We study the phase diagram and quantum critical region of one of the fundamental models for electronic correlations: the periodic Anderson model. Employing the recently developed d…

Why the critical temperature of high- cuprate superconductors is so low: The importance of the dynamical vertex structure
Motoharu Kitatani, Thomas Schäfer, Hideo Aoki +1
To fathom the mechanism of high-temperature () superconductivity, the dynamical vertex approximation (DA) is evoked for the two-dimensional repulsive Hubbard model. A…
