...Drew A. Cheney; Jennifer R. Lukes We present a new computational method that excites guided phonon modes in nanoscale waveguides at a specific frequency and wavenumber. The method uses nonequilibrium molecular dynamics and Fourier analysis of particle displacements to extract mode shapes from...

... that conventional Fourier analysis leads to erroneous thermal predictions when the mean free path of heat carriers is comparable to or larger than the characteristic domain size. This is also true when the time scale of interest is smaller than the relaxation time of the carriers 1 2 . When the system length...
