Heat conduction in a one-dimensional Yukawa chain is investigated. It is shown that the heat conductivity is abnormal in the absence of external potential. Effects of symmetric and asymmetric external potentials on the heat conduction of the system are also studied. It is found that the heat fluxes along opposite directions can be significantly different. One can control the heat flux through the external potential, which can induce a conductor-insulator transition of the system.
