Frenkel-Kontorova (FK) lattices with a coupling displacement was investigated.Through simplifying the model, we derived analytical expression of thermal current of the system in the overdamped case.By
Real systems contain inevitably disorders, for example impurities, whose effects on phase transitions are thus of great importance.According to different strength of the interaction between spin pairs
The principle governing the evolution of transportation network is discussed.It is argued that new edges should be added in the network to increase the network efficiency as much as possible.The evolu
