## Description

- description: As a long-standing topic, phonon hydrodynamics, owing to its unique
    collective transport physics, motivates theoreticians and experimentalists to
    explore it in micro-and nano-scale and at elevated temperatures nowadays. With
    its intrinsically strong normal scattering, graphitic materials have been predicted
    to facilitate hydrodynamic heat transport. However, the observation of phonon
    Poiseuille flow in graphitic samples remains a challenging task due to the experimental
    difficulties and missing theoretical understanding. Here, based on a micro-scale
    experimental platform and the pertinent occurrence criterion in anisotropic solids,
    we clearly demonstrate the phonon Poiseuille flow in a 5 μm-wide suspended graphite
    ribbon with purified 13C isotope concentration. Our observation is well supported
    by theoretical results based on kinetic theory with fully first-principles input.
    This work thus paves the way for deeper insight into phonon hydrodynamics and
    cutting-edge heat manipulating applications.
