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…
Doping-driven Mott transition in La_{1-x}Sr_xTiO_3 via simultaneous electron and hole doping of t2g subbands
A. Liebsch
The insulator to metal transition in LaTiO_3 induced by La substitution via Sr is studied within multi-band exact diagonalization dynamical mean field theory at finite temperatures…
Quantum phase transition in the two-band Hubbard model
T. A. Costi, A. Liebsch
The interaction between itinerant and Mott localized electronic states in strongly correlated materials is studied within dynamical mean field theory in combination with the numeri…
Coulomb correlations do not fill the e'_g hole pockets in Na_{0.3}CoO_2
A. Liebsch, H. Ishida
There exists presently considerable debate over the question whether local Coulomb interactions can explain the absence of the small e'_g Fermi surface hole pockets in photoemissio…
