Buried topological edge state associated with interface between topological band insulator and Mott insulator
H. Ishida, A. Liebsch
The electronic structure at the interface between a topological band insulator and a Mott insulator is studied within layer dynamical mean field theory. To represent the bulk phase…
Coulomb blockade and Kondo effect in the electronic structure of Hubbard molecules connected to metallic leads: a finite-temperature exact-diagonalization study
H. Ishida, A. Liebsch
The electronic structure of small Hubbard molecules coupled between two non-interacting semi-infinite leads is studied in the low bias-voltage limit. To calculate the finite-temper…
Correlation induced spin freezing transition in FeSe: a dynamical mean field study
A. Liebsch, H. Ishida
The effect of local Coulomb interactions on the electronic properties of FeSe is explored within dynamical mean field theory combined with finite-temperature exact diagonalization.…
Mott transition in two-dimensional frustrated compounds
A. Liebsch, H. Ishida, J. Merino
The phase diagrams of isotropic and anisotropic triangular lattices with local Coulomb interactions are evaluated within cluster dynamical mean field theory. As a result of partial…
The Mott insulator LaTiO_3 in heterostructures with SrTiO_3 is metallic
H. Ishida, A. Liebsch
It is shown that LaTiO_3 in superlattices with SrTiO_3 is not a Mott insulator but a strongly correlated metal. The tetragonal lattice geometry imposed by the SrTiO_3 substrate lea…
Effect of Dynamical Coulomb Correlations on the Fermi Surface of Na_0.3CoO_2
H. Ishida, M. D. Johannes, A. Liebsch
The t2g quasi-particle spectra of Na_0.3CoO_2 are calculated within the dynamical mean field theory. It is shown that as a result of dynamical Coulomb correlations charge is transf…
