Disorder-induced vibrational anomalies from crystalline to amorphous solids
The origin of the boson peak—an excess of the density of states over Debye's model in glassy solids—is still under intense debate, among which some theories and experiments suggest that the boson peak is related to a van-Hove singularity. Here we show that the boson peak and the van-Hove singul...
