We are focusing on design, growth, and analysis of correlated oxide interfaces showing a variety of outstanding properties. We control symmetry, dimensionality, and topology of materials through atomically flat interfaces mainly by pulsed-laser-deposition thin film growth; this will open up a way to novel quantum matter. For example, we can “smoothly” control dimensionality of correlated oxides by forming superlattices; this enables us to thoroughly explore quantum phase diagrams, leading to discovery of new phase transitions. We also utilize symmetry; inversion symmetry is always broken at interfaces, resulting in antisymmetric magnetic interaction known as Dzyaloshinskii-Moriya interaction. This provides possible spintronic applications at well-defined epitaxial oxide interfaces. Through these interfaces, we try to understand nature of novel quantum matters and to bring out their functionalities.
