　In this PRESTO research area, we aim to create innovative materials that contribute to solving social issues and improving human happiness by understanding and controlling spatial fluctuations, such as heterogeneity and defects, and temporal fluctuations, such as dynamics and non-equilibrium phenomena.
　Recent advances in materials research include the development of measurement techniques using high-intensity synchrotron radiation, high-intensity neutron beams, high-precision electron microscopes, and scanning probe microscopes, as well as the dramatic improvement in computer performance, as typified by the supercomputer Fugaku, and advances in materials simulation methods. The development of AI and data science methods also supports these. Materials informatics, which uses experimental and simulation data to search for novel materials, is also progressing.
　We will utilize these advances in measurement technology and computer science to gain a fundamental understanding and control of fluctuations. we will focus on the material properties that arise from spatial and temporal fluctuations in structure, defects, composition, ions, molecules, orientation, etc., and aim to create materials with dramatically improved performance by elucidating the principles and mechanisms involved. We will also make the fundamental technologies that will form the basis of this research, including analytical measurement technology, simulation technology, data analysis technology, and process technology.
