Recent findings of topological band structures in two-dimensional electron gases (2DEGs) at surfaces and interfaces of transition metal oxides are opening up new perspectives for the engineering of multifunctional materials. Spin-orbit interactions are enhanced at boundaries and their sizable magnitude can be tuned by gates effectively modulating the superconductivity and the spintronic regime that are found in these 2DEGs. Spin-orbit and Coulomb interactions also affect the topological character of the bands.
