Microscopic buckling and low-energy dynamics in glasses

This paper presents a general approach for the description of peculiar dynamic properties of glasses observed at low temperatures and low energies, These are the specific heat linear in temperature, the plateau in the thermal conductivity and its subsequent rise above the plateau temperature, as well as the increased inelastic scattering of light and neutrons at around 5 meV, the so-called Boson peak. The approach naturally accounts for in a unified way the characteristic features observed at low temperatures and low energies for a wide variety of glassy materials.
