A note on a unified theory of thermal transport in crystals and disordered solids

We propose an extension to the original result derived by Simoncelli et al. (https://doi.org/10.1038/s41567-019-0520-x) to encompass the effects of a space and time dependent heat source. Via a Fourier Transfrom, we obtain closed form expressions for the dynamics of the phonon population and coherence as a function of heat source.
