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…

An embedding potential definition of channel functions
J E Inglesfield, S Crampin, H Ishida
We show that the imaginary part of the embedding potential, a generalised logarithmic derivative, defined over the interface between an electrical lead and some conductor, has orth…
