Observation of Ballistic Thermal Transport in a Nonintegrable Classical Many-Body System
Jianjin Wang, Daxing Xiong
We report, for the first time, the observation of ballistic thermal transport in a nonintegrable classical many-body system. This claim is substantiated by appropriately incorporat…

Antipersistent energy current correlations in strong long-ranged Fermi-Pasta-Ulam-Tsingou type models
Daxing Xiong, Jianjin Wang
We study heat transfer in one-dimensional Fermi-Pasta-Ulam-Tsingou type systems with long-range (LR) interactions. The strength of the LR interaction between two lattice sites deca…

Thermal conductivity in one-dimensional nonlinear disordered lattices: Two kinds of scattering effects of hard-type and soft-type anharmonicities
Jianjin Wang, Chi Xiong, Daxing Xiong
The amorphous solids can be theoretically modeled by anharmonic disordered lattices. However, most of theoretical studies on thermal conductivity in anharmonic disordered lattices…
