greenWTE: Frequency-domain solver for the phonon Wigner Transport Equation with arbitrary heating using Green's functions
Laurenz Kremeyer, Bradley J. Siwick, Samuel Huberman
Heat transport in solids is usually described in a phenomenological way via Fourier's law. However, at small time and length scales in low thermal conductivity materials, a microsc…

Transition from population- to coherence-dominated nondiffusive thermal transport
Laurenz Kremeyer, Bradley J. Siwick, Samuel Huberman
Deviations from diffusive heat transport in high thermal conductivity crystalline insulators are generally understood within the framework of the phonon Boltzmann Transport Equatio…
