Abstract:
We consider the harmonic and anharmonic chains of oscillators with
self-consistent stochastic reservoirs and derive an integral representation
(à 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.
Keywords:
harmonic crystal, anharmonic crystal, stochastic reservoirs, heat flow.
