HEAT CONDUCTION IN DIELECTRIC ATOMIC CHAINS WITH ON-SITE POTENTIAL

Heat conduction in dielectric atomic chains with on-site potential were studied by means of FKM formalism. Using numerical simulation we found that the on-site potential plays an important role in quantum thermal transport. As special clases, the "Fourier-like behavior" J proportional to 1/N was obtained also for different boundary conditions. The influence of boundaries can be regulated by the coupling strength coefficient of the on-site potential.
