“…The coherent phonon transport is observed indirectly by the characterization of macroscopic variables, such as the non-monotonic variation of the thermal conductivity with the period length in phononic crystal structures [36,52], the variation of thermal conductivity with boundary roughness [71] or aperiodic structures [54,72], and temperature oscillation effect in superlattice [73]. Interested readers can refer to recent reviews [34][35][36] on the effect of coherent phonon transport on thermal conductivity. Moreover, phonon coherence manifests in various ways, such as hybridized phonon modes, phonon localization, and modal phonon interference.…”

“…In recent decades, experimental, theoretical, and computational developments have promoted the understanding of nanoscale heat conduction . Recent advances in various interesting phonon phenomena, such as hydrodynamic phonon transport [31][32][33], coherent phonon transport [34][35][36], interfacial thermal transport [1], and phononmagnon interaction [37], have been reviewed. Moreover, emerging phonon phenomena similar to electron transport have been discovered, such as hydrodynamic phonon transport [31,32], phonon coherence [26,38], weak coupling [39], and topological and high-order anharmonicity of phonon [40][41][42][43][44][45].…”

Recently, emerging phonon phenomena have been discovered and rapidly developed, which have become an active hot research topic. In this review article, we present state-of-the-art advances in several fascinating phonon transport phenomena. First, we summarize the recent progress on the wave nature of phonons, including phonon coherence and its effects on thermal conductivity and the topological properties of phonons. Then, we discuss the particle nature of phonons, including the weak coupling of phonons and the high-order phonon anharmonicity. Finally, we present the summary and a brief outlook. This review presents the advanced understanding of some emerging phonon phenomena in solid materials, which provides new opportunities for further advancement in a wide variety of applications.

“…In addition, the zero-point energy should be included in the phonon occupation number when the temperature is above onethird of T D . [249] At low temperature, other methods, such as Monte Carlo simulations [213,[250][251][252][253][254][255][256] and ab initio calculations [257][258][259] mainly based on the discussion in Section 3.2.1, are more applicable to obtain κ and have been largely applied in recent literature on PnCs and MMs. Other methods, such as the Allen-Feldman theory for disordered harmonic solids [260] and atomistic Green's function method, [261] have also been widely used to study phonon transport, however, with constraints, including the negligence of anharmonicity, which requires further adaptations in their applications.…”

free carrier creation and electron-phonon relaxations allowing the dissipation of the laser pulse energy into phonons. [6] For instance, Hudert and co-workers [7] demonstrated that femtosecond pulses are generating coherent acoustic phonons in silicon membranes, the latter phonons being detected by monitoring the changes of the dielectric constant in a pump probe experiment. In 1996, Hase and co-workers demonstrated that such coherent acoustic phonons, generated in a bismuth thin film, are interfering when generated by two delayed pulses. [8] Other experiments on thin films have demonstrated acoustic phonons propagation and reflections in layered media yielding to the determination of their velocity and their energy [7] and the fabrication of multilayered media or phononic crystals offers way of manipulating coherent acoustic phonons. [9] As such ultrafast lasers related techniques are offering a large avenue to study and control phonons at nanoscale in order to establish the design rules for future heat sinks at nanoscale. However, once miniaturization is pushed to its lower limit reaching, standard pump-probe reflection techniques relying on the detection of phonon wave propagation and reflection in thin films [7,8] are not relevant anymore when nanostructure dimensions are of the order of magnitude of optical wavelengths. Alternative approaches are required to investigate the phonons properties of acoustic phonon frequency.To address this bottleneck, we have implemented an alternative approach to probe high frequency phonons up to in the 1 to 20 THz range relying on inelastic scattering spectroscopy coupled to femtosecond pulses. Our approach allows to directly access to the acoustic phonon spectrum, which usually require to collect the time-dependent reflectivity Fourier transform. [7,8] Furthermore, we demonstrate that the temporal and spectral shaping of femtosecond pulses controls this coherent acoustic phonon emission spectrum in silicon metasurfaces.
