Electronics with correlated oxides: SrVO/SrTiO as a Mott transistor
Zhicheng Zhong, Markus Wallerberger, Jan M. Tomczak +5
We employ density functional theory plus dynamical mean field theory and identify the physical origin of why two layers of SrVO on a SrTiO substrate are insulating: the thi…
Importance of d-p Coulomb interaction for high T cuprates and other oxides
Philipp Hansmann, Nicolaus Parragh, Alessandro Toschi +2
Current theoretical studies of electronic correlations in transition metal oxides typically only account for the local repulsion between d-electrons even if oxygen ligand p-states…
Correlation effects in transport properties of interacting nanostructures
A. Valli, G. Sangiovanni, A. Toschi +1
We discuss how to apply many-body methods to correlated nanoscopic systems, and provide general criteria of validity for a treatment at the dynamical mean field theory (DMFT) appro…
From infinite to two dimensions through the functional renormalization group
C. Taranto, S. Andergassen, J. Bauer +5
We present a novel scheme for an unbiased and non-perturbative treatment of strongly correlated fermions. The proposed approach combines two of the most successful many-body method…
Poor Man's Understanding of Kinks Originating from Strong Electronic Correlations
K. Held, R. Peters, A. Toschi
By means of dynamical mean field theory calculations, it was recently discovered that kinks generically arise in strongly correlated systems, even in the absence of external bosoni…
Mott-Hubbard transition in V2O3 revisited
P. Hansmann, A. Toschi, G. Sangiovanni +4
The isostructural metal-insulator transition in Cr-doped V2O3 is the textbook example of a Mott-Hubbard transition between a paramagnetic metal and a paramagnetic insulator. We rev…
