This project aims to develop a new three-dimensional (3D) magnetic-imaging technique to explore and observe 3D topological spin textures in magnets such as skyrmion-strings, magnetic hedgehogs (monopoles), and hopfions. Using the developed imaging technique, we will open a new paradigm of the topological-magnetism science for the upcoming beyond-skyrmion era by predicting, exploring and verifying emergent phenomena and materials functions of newly discovered topological magnets and topological spin textures.

We verify the emergence of Majorana states in electric circuits by simulating a topological superconductor model. Then, demonstrating that braidings of Majorana states act as quantum gates, we perform basic experiments showing that topological quantum computations are executable based on electric circuits. In addition, we develop variable-electronic elements and ideal-electronic elements necessary for the realization of our proposal. We pave a way to a large-scale implementation based on analogue and digital integrated circuits applying the knowledge of electromechanical systems.

We develop and engineer precisely-designed 2D materials, such as nanoribbons and two-dimensional / three-dimensional networks, and establish topological band engineering in 2D materials. By combining condensed matter theory, organic chemistry and materials engineering, we theoretically design 2D-material-based superstructures with non-trivial topological electronic properties, fabricate them with the aid of nano-space technology on metal organic framework (MOF), and develop innovative electronic devices.

We fabricate topological organic microstructures by precise control of the self-assembly process of molecules. We will construct a laser devices with topological characters such as highly-directional circularly polarized lasers, optical vortex lasers from topological edge optical cavities and room temperature polariton propagation control devices. These devices will be utilized for highly sensitive optical sensing in response to changes in the external environment.
