Asymmetric Heat Conduction in Nonlinear Lattices
Asymmetric Heat Conduction in Nonlinear Lattices
In this Letter, we conduct an extensive study of the two-segment Frenkel-Kontorova model. We show that the rectification effect of the heat flux reported in recent literature is possible only in the weak interfacial coupling limit. The rectification effect will be reversed when the properties of the interface and the …
