Thermal Conductivity in Low-Dimensional Nonlinear Lattices
Heat transport in an electrically insulating material is attributed to lattice vibrations and is described in terms of the phenomenological theory referred to as Fourier’s law. A number of simulations using molecular dynamics have been performed to verify Fourier’s law in low-dimensional lattices from first principles[1–4]. However, most attempts failed [1–4] to present the normal thermal conductivity without external disturbances since the resultant conductivity was dependent on system size.
