    "abstract": "We investigate the mechanism of heat conduction in ordered and disordered\nharmonic onedimensional chains within the quantum mechanical Langevin method.\nIn the case of the disordered chains we find indications for normal heat\nconduction which means that there is a finite temperature gradient but we\ncannot clearly decide whether the heat resistance increases linearly with the\nchain length. Furthermore we observe characteristic quantum mechanical features\nlike Bose-Einstein statistics of the occupation numbers of the normal modes,\nfreezing of the heat conductivity and the influence of the entanglement within\nthe chain on the current. For the ordered chain we recover some classical\nresults like a vanishing temperature gradient and a heat flux independent of\nthe length of the chain.",
