要旨: In our lives, there are two types of solid-states materials. One is crystals, and the other is noncrystalline, glasses. We already have a good level of understanding of crystals. Their thermal and transport properties can be described in terms of phonons; their heat capacity and thermal conductivity are well described by the Debye theory and the phonon-gas theory, respectively. By contrast, we have only a limited understanding of glasses that exhibit fundamentally different properties from those of crystals. Because glasses are materials commonly encountered in our daily lives and are widely employed in modern technologies (examples include silicate glasses, metallic glasses, plastic materials, ceramics, and many other rigid, disordered materials), their understanding is crucial not only in physics and materials science but also in engineering. In this seminar, I would introduce the latest progress in understanding of glasses.
