Unified theory of vibrational spectra in amorphous materials
Matteo Baggioli, Alessio Zaccone
The phonon spectra of solids, described through the measurable vibrational density of states (VDOS), provide a wealth of information about the underlying atomic structure and bondi…
Theory of the phonon spectrum in host-guest crystalline solids with avoided crossing
Matteo Baggioli, Bingyu Cui, Alessio Zaccone
We develop an analytical model to describe the phonon dispersion relations of host-guest lattices with heavy guest atoms (rattlers). Crucially, the model also accounts for phonon d…
Hydrodynamics of disordered marginally-stable matter
Matteo Baggioli, Alessio Zaccone
We study the vibrational spectra and the specific heat of disordered systems using an effective hydrodynamic framework. We consider the contribution of diffusive modes, i.e. the 'd…
Vibrational density of states and specific heat in glasses from random matrix theory
Matteo Baggioli, Rico Milkus, Alessio Zaccone
The low-temperature properties of glasses present important differences with respect to crystalline matter. In particular, models such as the Debye model of solids, which assume th…
