Comparison with the soft-mode model 330 $aThe present book describes the fundamental features of glassy disordered systems at high temperatures (close to the liquid-to-glass transition) and for the first time in a book, the universal anomalous properties of glasses at low energies (i.e. temperatures/frequencies lower than the Debye values) are depicted. Several important theoretical models for both the glass formation and the universal anomalous properties of glasses are described and analyzed. The origin and main features of soft atomic-motion modes and their excitations, as well as their role in the anomalous properties, are conside 606 $aOptics 606 $aGlass 608 $aElectronic books. 615 0$aOptics. 615 0$aGlass. 676 $a620.1/44 676 $a620.144 700 $aKlinger$b Michael I$0968222 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910462803403321 996 $aGlassy disordered systems$92199124 997 $aUNINA
