Monte Carlo Study of Non-diffusive Relaxation of A Transient Thermal Grating in Thin Membranes
Lingping Zeng, Vazrik Chiloyan, Samuel Huberman +5
The impact of boundary scattering on non-diffusive thermal relaxation of a transient grating in thin membranes is rigorously analyzed using the multidimensional phonon Boltzmann eq…
A Variational Approach to Extracting the Phonon Mean Free Path Distribution from the Spectral Boltzmann Transport Equation
Vazrik Chiloyan, Lingping Zeng, Samuel Huberman +3
The phonon Boltzmann transport equation (BTE) is a powerful tool for studying non-diffusive thermal transport. Here, we develop a new universal variational approach to solving the…
No energy transport without discord
Seth Lloyd, Zi-Wen Liu, Stefano Pirandola +4
We show that without quantum correlations, energy cannot flow. The result follows from a simple theorem that shows that systems whose dynamics do not generate quantum discord are e…
Ab initio optimization of phonon drag effect for lower-temperature thermoelectric energy conversion
Jiawei Zhou, Bolin Liao, Bo Qiu +4
While the thermoelectric figure of merit zT above 300K has seen significant improvement recently, the progress at lower temperatures has been slow, mainly limited by the relatively…
