Abstract
Glass, gel, or soft matter material near the phase transition point has high symmetry and various physical quantities are spatially uniform. Such uniformity is isotropic and highly transparent and has practically important and useful physical properties. On the contrary, high symmetry makes observation by structural analysis equipment such as microscopes and X-rays ineffective and is a major obstacle to material design and synthesis based on physical property measurement. Therefore, we recently found a new principle of a fluctuation microscope for observing dynamic inhomogeneities in soft matter and completed a prototype. In gel, glass and mixed or complex systems containing different species of molecules, cooperative dynamic modes appear hierarchically based on local molecular motion, even if they are liquid state without static material structure. appear. This fluctuation microscope directly visualizes the dynamic spatial inhomogeneity of such fluctuations in modes of collective motions.
