J. Phys. 37 (1959) 334]) suffered from a paradox: this resistance erroneously tends to a finite value in the limit of identical solids. We resolve this paradox by calculating temperature differences in the final heat-transporting state, rather than with respect to the initial state of local equilibrium. We thus derive an exact, paradox-free formula for the boundary resistance. We compare the definition of local temperatures in terms of ""nonequilibrium"" energy densities with the (phase-sensitive) measurement of such a temperature by attaching a probe to the system, and find considerable agreement between the two. The analogy to ballistic electron transport is explained.","Physics; Kapitza resistance; Heat transport; Temperature measurement","en","article","","","","","","","","","","","","","",""

J. Phys. 37 (1959) 334; Leung and Young, Phys. Rev. B 36 (1987) 4973) to lead to apparently paradoxical results in the limit of identical solids: instead of vanishing, the resistance tends to a finite limit. We resolve this paradox by calculating temperature differences in the final heat-transporting state of the system, i.e., not in the initial state of local equilibrium. For a quantum mechanical model of an interface between harmonic solids with temperature probes attached, exact calculations relate the probe temperatures to non-equilibrium energy densities. The analogy with two- and four-terminal resistance measurements in ballistic electron transport is also discussed.","Physics; Acoustic wave transmission; Electron transport properties; Heat transfer; Interfaces (materials); Solids; Temperature measurement; Ballistic electron transport; Harmonic solids; Kapitza boundary resistance; Phonons","en","article","","","","","","","","","","","","","",""
