Anomalous Heat

Heat conduction in one-dimensional lattice with double-well interaction potential is studied numerically in different temperature regions. In the low temperature case, different structures such as order, period-2, and disorder structure phases, lead to different anomalous heat conduction. In a shallow intermediate temperature region, the heat conductivity is finite in a large system size. When temperature increases high enough, the heat conduction is anomalous, as well as FPU-β model.
