Nickelate superconductors -- a renaissance of the one-band Hubbard model
Motoharu Kitatani, Liang Si, Oleg Janson +3
Following the discovery of superconductivity in the cuprates and the seminal work by Anderson, the theoretical efforts to understand high-temperature superconductivity have been fo…

Pairing and non-Fermi liquid behavior in partially flat-band systems
Sharareh Sayyad, Edwin W. Huang, Motoharu Kitatani +4
While multiband systems are usually considered for flat-band physics, here we study one-band models that have flat portions in the dispersion to explore correlation effects in the…

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…
