## Description

- description: "Boson peak dynamics in glasses produce a robust crossover in the terahertz
    (THz) dielectric response that standard Debye or Lorentz models do not capture.
    We develop a continuum description of this THz response, coupling an infrared-effective
    charge fluctuation spectrum to a frequencydependent\r\nshear modulus, and apply
    it to glycerol glass. The model reproduces the measured complex dielectric function
    and the nearly linear infrared light-vibration coupling around the boson peak,
    and highlights the dominant role of transverse shear dynamics."
