We are interested in electron-transport phenomena in nano-scale systems composed of different types of functional materials such as ferro- and antiferro-magnetic materials, superconductor, normal metal and insulator. Especially, we focus significantly on the influence of electron spin in the transports, so called spin-dependent transports. Moreover, understanding and manipulating the dynamical motions of spin is also important research subject. The specific example of the research subject is as follows.
Understanding electrically and thermally driven spin-current transports
Interplay between spin-polarized electron and cooper pair
Nonlinear motion of nano-scale spin dynamics in patterned ferromagnetic film
Development of novel nanoelectric devices such as spin memristor and spin filter
We are the experimental research group that investigates Non-equilibrium Physics of “soft materials” (e.g. colloids, polymers and liquid crystals). Much of the diversity in nature depends on the complex hierarchical ordering of these soft materials and their slow cooperative dynamics, that are the focus of our study. Dynamic self-assembly of soft materials, for instance, creates exquisite structures in living organisms that are under constant activation by their own metabolism. We investigate such nonequilibrium processes that obviously do not obey the statistics of thermodynamic equilibrium, by developing novel state-of-the-art experimental and theoretical techniques.Read more

Why living organisms consist of soft materials? Complexity and versatility of biological systems arise when soft materials are driven far from equilibrium. We investigate the mechanism from physics perspectives, by measuring "softness" and "non-equilibrium properties" of soft matter.
