Probing the validity of the diffuse mismatch model for phonons using atomistic simulations
Rohit R. Kakodkar, Joseph P Feser
Due to it's simplicity the diffuse mismatch model (DMM) remains a popular description of phonon transmission across solid-solid boundaries. However, it remains unclear in which sit…

A framework for solving atomistic phonon-structure scattering problems in the frequency domain using Perfectly Matched Layer boundaries
Rohit R. Kakodkar, Joseph P. Feser
We present a numerical approach to the solution of elastic phonon scattering problems based on a frequency domain decomposition of the atomistic equations of motion and the use of…
