Acesso em: 20 jul. 2017.1573-9333http://www.repositorio.ufop.br/handle/123456789/8739We consider the harmonic and anharmonic chains of oscillators with self-consistent stochastic reservoirs and derive an integral representation (`a la Feynman–Kac) for the correlations, in particular, for the heat flow. For the harmonic chain, we give a new proof that its thermal conductivity is finite in the steady state. Based on this integral representation for the correlations and a perturbative analysis, the approach is quite general and can be extended to more intricate systems.en-USrestritoHarmonic crystalHeat flowArtigo publicado em periodicohttps://link.springer.com/article/10.1007/s11232-008-0100-1https://doi.org/10.1007/s11232-008-0100-1
