Unified theory of thermal transport in crystals and glasses
TL;DR: In this paper, a unified theory for the conduction of heat in materials is derived and shown to account for both the limiting regimes of periodic crystals and aperiodic glasses, respectively, in anharmonic crystals or harmonic glasses, while also covering the intermediate regimes where both effects are relevant.

Unified theory of thermal transport in crystals and disordered solids
TL;DR: In this article, the authors derived a transport equation for thermal conductivity that reduces to the Peierls and Allen-Feldman limits in anharmonic and ordered or harmonic and disordered solids, while also covering the intermediate regimes where both effects are relevant.

Generalization of Fourier’s Law into Viscous Heat Equations
TL;DR: In this paper, two novel differential equations for heat conduction in crystals generalize Fourier's law and explain why heat propagation can become fluidlike, rather than diffusive, in electronic or phononic devices.

Generalization of Fourier's law into viscous heat equations
TL;DR: In this paper, it was shown that the complementary set of even relaxons determines another quantity, thermal viscosity, that enters into the description of heat transport, and is especially relevant in the hydrodynamic regime, where dissipation of crystal momentum by Umklapp scattering phases out.

Thermal conductivity of glasses: first-principles theory and applications
TL;DR: In this article , the authors present a protocol to predict the thermal conductivity of glasses above the plateau (i.e., above the temperature-independent region appearing almost without exceptions in the κ (T ) of all glasses at cryogenic temperatures).
