Abstract: The intersection of emergent phenomena, e.g., ferroelectricity, magnetism, and superconductivity, is a fertile landscape for exotic quantum orders. In this presentation, I will talk about engineering these cooperative orders in complex oxides and chalcogenide thin films and heterostructures. I will present our recent results on molecular beam epitaxy (MBE) growth of KTaO3 heterostructures and the emergence of long-range polarization and two-dimensional superconductivity in this system. I will also talk about the emergence of a magnetic order in KTaO3, a nominally nonmagnetic system. Finally, I will present our recent results on MBE growth and engineered intersections between ferroelectricity and superconductivity in Pb1-xSnxTe.
