The Fermi-Pasta-Ulam-Tsingou problem after 70 years: toward universal laws of thermalization in lattice systems in the thermodynamic limit
Weicheng Fu, Zhen Wang, Wei Lin +4
The Fermi--Pasta--Ulam--Tsingou (FPUT) problem provides a paradigmatic framework for understanding thermalization in weakly nonlinear many-body Hamiltonian systems. This focused re…
From Near-Integrable to Far-from-Integrable: A Unified Picture of Thermalization and Heat Transport
Weicheng Fu, Zhen Wang, Yisen Wang +2
Whether and how a system approaches equilibrium is central in nonequilibrium statistical physics, crucial to understanding thermalization and transport. Bogoliubov's three-stage (i…
Multi-Type Instability Processes of Periodic Orbits in Nonlinear Chains
Weicheng Fu, Zhen Wang, Yong Zhang +1
Nonlinear normal modes are periodic orbits that survive in nonlinear many-body Hamiltonian systems, and their instability is crucial for relaxation dynamics. Here, we study the ins…
A general multi-wave quasi-resonance theory for lattice energy diffusion
Wei Lin, Weicheng Fu, Zhen Wang +2
In this letter, a multi-wave quasi-resonance framework is established to analyze energy diffusion in classical lattices, uncovering that it is fundamentally determined by the chara…
Nonintegrability-driven Transition from Kinetics to Hydrodynamics
Weicheng Fu, Zhen Wang, Yisen Wang +2
Nonintegrability plays a crucial role in thermalization and transport processes in many-body Hamiltonian systems, yet its quantitative effects remain unclear. To reveal the connect…
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…
