Using nonequilibrium molecular dynamics simulations, we investigate thermal rectification in mass-graded lattices with a new type on-site potential which has a physical picture of the double-well. By adjusting the ratio of harmonic on-site potential and anharmonic on-site potential, we could obtain the optimal heat transport and the best thermal rectification. In addition, we observe the reversal thermal rectification by changing the ratio of on-site potential and analyzes the mechanism of thermal rectification through the power spectrum. At last, we also study the heat flux and thermal rectification in a different case of average temperature and mass gradient.

Model Approach

We demonstrate using two examples that a minimal model of a spin system can present qualitative correct magnetization plateaus which are almost the same as the original model. Some arguments on the generality of the minimal model approach are given. The approach can serve as a primary approximation and a assistance to the analytical and numerical methods.
