Title:
Novel Electronic Phenomena at Oxide Interfaces

Abstract:
The ongoing search for new platforms for electronics and spintronics recently came to fruition in the form of oxides interfaces. For example, it has been demonstrated that the interface layer between the non-magnetic insulators LaAlO3 and SrTiO3 has a very rich phase diagram. In addition to metallic and magnetically ordered phases, it also exhibits an unusual state where superconductivity and ferromagnetism coexist. In my talk, I will present a model of the electronic structure of the LaAlO3/SrTiO3 interface that explains its unexpected properties. In particular, this model clarifies the origin of ferromagnetism and its coexistence with superconductivity. An important ingredient is the strong spin-orbit coupling generated at the interface. I will show that this can stabilize a variant of the Fulde-Ferrel-Larkin-Ovchinikov up to high magnetic fields. Surprisingly, this unconventional condensate of Cooper pairs at finite momentum survives even strong disorder. I will describe the mechanism behind this phenomenon and discuss experimental consequences.
