Heat conduction through the Frenkel-Kontorova lattices is numerically investigated in the presence of a deformable substrate potential. It is found that the deformation of the substrate potential has a strong influence on heat conduction. The thermal conductivity as a function of the shape parameter is nonmonotonic. The deformation can enhance thermal conductivity greatly, and there exists an optimal deformable value at which thermal conductivity takes its maximum. Remarkably, we also find that…

TLDR
The proposed NDTR system provides theoretical insights for the design of certain thermal devices and non-equilibrium molecular dynamics simulations and kinetic theory analyses show that the heat flux through the system can be suppressed and even prohibited when the temperature difference across the system becomes sufficiently high.

TLDR
This paper studies the interfacial thermal transport between two nonlinear materials by using a one-dimensional FPU-β heterojunction model through molecular dynamics simulation and finds that the ITR first decreases rapidly and then increases slowly with the increase of interface coupling coefficient (ICC).
