摘要：
Thermal conduction in a one-dimensional anharmonic lattice is investigated with the use of homogeneous nonequilibrium molecular dynamics. This approach enables us to obtain thermal conductivity as a function of temperature. Coherent excitations are observed to play an important role in transporting energy, especially when an external ''field'' becomes large.
