Abstract
Non-linear phonon dynamics in the dielectric ordered linear chain is investigated by non-equilibrium molecular dynamics. By considering the coupling with the heat baths, the expression for the heat flow (analogous to J= {Sigma}{sub k}E{sub k}v{sub k} found by Peierls for periodic systems) is found for the chain with free- and rigid-boundary conditions. Differences in the dynamics of energy transport between periodic-, free- and rigid-boundary conditions are discussed. Moreover, it is shown that the total flow can be separated as a contribution of N wave packets, where N is the number of degrees of freedom. The expressions for the flow of the wave packets are reported for both rigid- and free-boundary conditions.
