Abstract
We study the superlubricity in the generalized Frenkel–Kontorova model. Each particle of the top layer is driven by external dc driving force Fext. When the ratios of the three inherent length scales of the system are chosen to be the Golden Mean (a/b=233/144,c/a=144/89), we find that there exists a critical interparticle interaction strength above which the static friction force Fsu of the top layer is zero. And Fsu could easily flow into the low friction with existing the lubricant layer.
