Thermal rectification and negative differential thermal resistance in lattices with mass gradient
Nuo Yang, Nianbei Li, Lei Wang +1
We study thermal properties of one dimensional(1D) harmonic and anharmonic lattices with mass gradient. It is found that the temperature gradient can be built up in the 1D harmonic…

Interface thermal resistance between dissimilar anharmonic lattice
Baowen Li, Jing-Hua Lan, Lei Wang
We study interface thermal resistance (ITR) in a system consisting of two dissimilar anharmonic lattices exemplified by Fermi-Pasta-Ulam (FPU) model and Frenkel-Kontorova (FK) mode…

Thermal diode: Rectification of heat flux
Baowen Li, Lei Wang, Giulio Casati
By coupling two nonlinear one dimensional lattices, we demonstrate a thermal diode model that works in a wide range of system parameters. We provide numerical and analytical eviden…
