- Glassy systems exhibit various universal anomalies compared to their crystalline counterparts, manifested in their vibrational, thermodynamic, transport and strongly dissipative properties. At the heart of understanding these phenomena resides the need to quantify glassy disorder, which is self-generated during the non-equilibrium glass formation process, and to identify the emerging elementary excitations. In this talk, I will review recent progress made in relation to this basic problem. Using a combination of theory, computer simulations and experimental data, I will elucidate the statistical and micro-mechanical nature and properties of low-frequency glassy (non-phononic) excitations, including their universal statistics, spatial localization, non-equilibrium history dependence, relations to spatially extended phonons and the emergence of a boson peak.
