　We explore quantum physics and its applications in fine structures of magnetic metals, strongly correlated electron systems, and superconductors designed with nanotechnology. Our goal is to establish physical principles for next-generation electronics by extracting quantum electronic and optical functions in terms of the manipulation of magnetic nanostructures and electron coherence. We also work on scanning probe techniques and other novel microscopic tools for characterizations of atomic and electronic structures, which serve as basic tools for investigation of novel properties in nanoscale, to explore surface physics in semiconductors, metals and organic materials.
