Toward quantum science innovation by exploring the spin physics
Our research targets solid-state physics stemming from "spin", a quantum of angular momentum i.e., spintronics, magnonics, gyromagnetics, strongly correlated systems, and topological physics. Exploiting the rectification nature of spin, we theoretically and experimentally pursue the potential of spin toward quantum science innovation that will be the basis of next generation energy-saving and energy-creating technologies.
Conservation of angular momentum
So far, we have pioneered "spin-hydrodynamic generation" that creates spin current from the vortex of liquid metal to generate electric power, "Barnett magnetometry" that measures the effective magnetic field that material rotation exerts on spin, and "spin Seebeck mechanical force" that causes material twist by spin current. Our theory work covers non-equilibrium magnon phenomena, the topological origins of spin and acoustic waves, the discovery of topological Hall torque, the emergent inductance with negative values, the calculation of spin-nematic quantum transport, and half-integer Shapiro steps in magnetic Josephson junctions.
