Abstract

Transition metal oxides exhibit a rich variety of collective phenomena already in the bulk due to a strong interplay of lattice, charge, spin and orbital degrees of freedom. Oxide interfaces open new possibilities for applications in electronics devices or for energy conversion due to the emergence of novel electronic phases that are not available the bulk constituents. In this talk I will review the insight obtained from density functional theory (DFT) calculations with an on-site Coulomb term how this novel functionality can be steered by a set of control parameters. Several examples will be discussed: (i) the prediction of topological Chern insulating phases and competition with Mott insulating states in oxide superlattices with a honeycomb [1] and dice pattern [2]; the emergence of a spin-polarized two-dimensional electron gas at the EuTiO 3 (001) surface and in LaAlO 3 /EuTiO 3 /SrTiO 3 (001) [3] (ii) the role of the film geometry [4] and the interface structure [5] in infinite-la...
