Exact Resonances Are Not Sufficient for Phonon Energy Diffusion
Wei Lin, Yong Zhang, Hong Zhao
Multi-phonon resonance conditions underpin kinetic theories of phonon transport and lattice thermalization. We show that exact resonance matching, nonzero interaction coefficients,…

Revisiting Multi-Wave Resonance in Classical Lattices: Quasi-Resonances, Not Exact Resonance, Govern Energy Redistribution
Wei Lin, Yong Zhang, Hong Zhao
The multi-wave exact resonance condition is a fundamental principle for understanding energy transfer in condensed matter systems, yet the dynamical evolution of waves satisfying t…
