Analytical and numerical solutions to the non-diffusive Stefan problem

Matthew Van Ham, Minghan Xu, Samuel Huberman

In this work, the Maxwell--Cattaneo--Vernotte (MCV) equation is used to model the one-dimensional hyperbolic Stefan problem in the limit of a small Stefan number (Ste 1). The…

Comment on "Fundamental limit of phonon Tesla valve for heat rectification from first principles"

Samuel Huberman, Aleksei Sokolov

Thermal rectification is a two-terminal property: the same device must carry different heat-current magnitudes when two reservoir temperatures are interchanged. In this Comment on…

Accounting for the length-scale dependence of thermal diffusivity in 3C-SiC measured with transient thermal gratings

Keshav Vasudeva, Samuel Huberman, Angus P. C. Wylie +7

Pump-probe optical methods like transient grating spectroscopy (TGS) enable rapid, nondestructive thermoelastic property measurements. But, in phonon-dominated ceramics, they can u…

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…

Probing carrier and phonon transport in semiconductors all at once through frequency-domain photo-reflectance

Qichen Song, Sorren Warkander, Samuel C. Huberman

Semiconductor devices favor high carrier mobility for reduced Joule heating and high thermal conductivity for rapid heat dissipation. The ability to accurately characterize the mot…

Ultrafast Electron Diffuse Scattering as a Tool for Studying Phonon Transport: Phonon Hydrodynamics and Second Sound Oscillations

Laurenz Kremeyer, Tristan L. Britt, Bradley J. Siwick +1

Hydrodynamic phonon transport phenomena, like second sound, have been observed in liquid Helium more than 50 years ago. More recently second sound has been observed in graphite at…
