Novel heat conduction model for bridging different space and time scales

This exposition describes a novel heat transport model and an underlying unified theory emanating from the physics of the Boltzmann transport equation which acknowledges simultaneously the coexistence of that termed as slow processes (at low energies) and fast processes (at high energies) as heat carriers while describing the evolution of heat transport characteristics spanning both spatial scales (characterizing ballistic to diffusive limits), and also time scales (characterizing finite to infinite heat propagation speeds).
