The anti-Fermi-Pasta-Ulam-Tsingou problem in one-dimensional diatomic lattices
Sihan Feng, Weicheng Fu, Yong Zhang +1
We study the thermalization dynamics of one-dimensional diatomic lattices (which represents the simplest system possessing multi-branch phonons), exemplified by the famous Fermi-Pa…

Thermalization in asymmetric harmonic chains
Weicheng Fu, Sihan Feng, Yong Zhang +1
The symmetry of the interparticle interaction potential (IIP) plays a critical role in determining the thermodynamic and transport properties of solids. This study investigates the…
