We derive the mode spectrum of the thermal boundary resistance between
two bodies having a temperature difference Delta T. A general expression
of the time iota that defines the resistance is derived as the
equilibrium autocorrelation of Delta T integrated over time. A further
decomposition of this autocorrelation yields the resistance spectrum as
equal to the mode relaxation time weighted by its energy mean square
fluctuation. We then perform molecular dynamics simulations of argon
like crystals in equilibrium and nonequilibrium regimes to prove the
relevance of our model. This general method allows for deriving the
resistance spectrum and therefore can yield key rules to control the
exchanged heat flux. (C) 2010 American Institute of Physics.
