Lattice Boltzmann scheme for hydrodynamic equation of phonon transport
Yangyu Guo, Moran Wang
In this work, a lattice Boltzmann scheme is developed for numerical solution of the phonon Boltzmann equation under Callaway's dual relaxation model in the hydrodynamic limit. Thro…
Quantum mechanical modeling of anharmonic phonon-phonon scattering in nanostructures
Yangyu Guo, Marc Bescond, Zhongwei Zhang +3
The coherent quantum effect becomes increasingly important in the heat dissipation bottleneck of semiconductor nanoelectronics with the characteristic size shrinking down to few na…
Self-synchronization of thermal phonons at equilibrium
Zhongwei Zhang, Yangyu Guo, Marc Bescond +3
Self-synchronization is a ubiquitous phenomenon in nature, in which oscillators are collectively locked in frequency and phase through mutual interactions. While self-synchronizati…
A generalized decay law for particle- and wave-like thermal phonons
Zhongwei Zhang, Yangyu Guo, Marc Bescond +3
Our direct atomic simulations reveal that a thermally activated phonon mode involves a large population of elastic wavepackets. These excitations are characterized by a wide distri…
