Abstract
We demonstrate the coherent transport of thermal energy in superlattices by introducing a microscopic definition of the phonon coherence length. We demonstrate how to distinguish a coherent transport regime from diffuse interface scattering and discuss how these can be specifically controlled by several physical parameters. Our approach provides a convenient framework for the interpretation of previous experiments and thermal conductivity calculations and paves the way for the design of a new class of thermal interface materials.

5 pages, 6 figures, 1 tables The method which is described is too sensitive to numerical noise. A new method has been developed and published in http://journals.aps.org/prb/abstract/10.1103/PhysRevB.90.014307
