Dynamics of Dielectrics with Intrinsic Inhomogeneity

Recent works have disclosed that intrinsic inhomogeneity of materials generates huge responses to weak outer field. A typical example is relaxor dielectrics, where the growth and fluctuation of polar nano-regions plays an important role in the soft dielectric properties. We expect the J-PARC to provide us direct evidences of the behavior of these intrinsic inhomogeneous structure of mesoscopic scale.
