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 Pb_1-xSn_xTe.

Bio: Kaveh Ahadi is an Assistant Professor at the Department of Physics and Materials Science & Engineering of North Carolina State University. He received his Ph.D. in materials science at the University of California, Santa Barbara (2019).  His current research focuses on correlated electrons and emergent phenomena at heterointerfaces; atomic-scale synthesis of heterostructures of quantum materials; low-dimensional superconductivity; oxide heterostructures for energy applications; and novel devices based on interface states.
