The purpose of this research area is to create materials and devices that have innovative functions unavailable through existing technology. This will be achieved by promoting research and development to contribute to both
　(1) the solution of a problem in relation to a new emerging function and (2) the creation of a material and device based on a new function, new principle, and new structure from the approach of a fundamental platform based on the idea of topology as a new substance focusing on the invariance under continuous deformation. It is expected that the new material and device will be implemented in the super-smart society in the future.
　For more specific research areas, we focus on condensed matter physics in relation to the topology of electronic states; we also include as our subjects the application to the fields of photonics and spintronics as well as device engineering that realizes new functions. In addition, our subjects include the topology in real space in addition to the control of spin current by using the topological characteristics such as topological defects, the soft matters to control the geometrical characteristics and entanglement of molecules.
　As these research fields are inter-linked in a complex manner, the measurement, analysis, and treatment processes for the solution and control of crystal growth technology, structure, and physical properties; the creation of technological platforms (such as part materials and/or device designing technology); and the construction of the fundamental scientific principle are also implemented as endeavors to create a material and device having a new innovative function.
