The effect of dressing on thermalization of interacting waves
Zhen Wang, Yong Zhang, Hong Zhao
We propose a more general setup for prethermalization in the system of interacting waves. The idea lies in dividing the multi-wave interactions into trivial and nontrivial ones. Th…
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…
Effect of pressure on thermalization of one-dimensional nonlinear chains
Weicheng Fu, Yong Zhang, Hong Zhao
Pressure plays a vital role in changing the transport properties of matter. To understand this phenomenon at a microscopic level, we here focus on a more fundamental problem, i.e.,…
Instability dynamics of nonlinear normal modes in the Fermi-Pasta-Ulam-Tsingou chains
Liangtao Peng, Weicheng Fu, Yong Zhang +1
Nonlinear normal modes are periodic orbits that survive in nonlinear chains, whose instability plays a crucial role in the dynamics of many-body Hamiltonian systems toward thermali…
Modified Stokes-Einstein Relation for Small Brownian Particles
Hanqing Zhao, Hong Zhao
The Stokes-Einstein (SE) relation has been widely applied to quantitatively describe the Brownian motion. Notwithstanding, here we show that even for a simple fluid, the SE relatio…
