Outline

Strong-Correlation Quantum Transport Research Team

We aim to study quantum transport in transition metal oxide heterostructures. Thus far, the concepts and techniques of mesoscopic physics have seldom been applied to most research in these materials, because of their typically low electron mean free paths. However, there has been significant progress in the growth of atomic scale oxide heterostructures, and a number of systems have been discovered which have metallic, magnetic and superconducting interfaces, some of which have sufficiently high mobility that interference experiments with normal state electrons are newly accessible. We propose to use these systems, in gated and lithographically-defined small structures, to probe mesoscopic effects in d-electron systems.
