Intrinsic Temporal Coherence Governs Heat Transport of Zone-Folded Phonons
Xiaoyu Huang, Yuxiang Ni, Zhongwei Zhang +4
While spatial phonon coherence manifested through band folding is believed to be a key factor governing the anomalous thermal conductivity of periodic structures, we investigate ph…
Observation of phonon Poiseuille flow in isotopically-purified graphite ribbons
Xin Huang, Yangyu Guo, Yunhui Wu +7
In recent times, the unique collective transport physics of phonon hydrodynamics motivates theoreticians and experimentalists to explore it in micro- and nanoscale and at elevated…
Assessing Phonon Coherence Using Spectroscopy
Zhongwei Zhang, Yangyu Guo, Marc Bescond +3
As a fundamental physical quantity of thermal phonons, temporal coherence participates in a broad range of thermal and phononic processes, while a clear methodology for the measure…
Heat conduction theory including phonon coherence
Zhongwei Zhang, Yangyu Guo, Marc Bescond +3
Understanding and quantifying the fundamental physical property of coherence of thermal excitations is a long-standing and general problem in physics. The conventional theory, i.e.…
