Anomalous frozen evanescent phonons by Yi Chen, Jonathan L. G. Schneider, Ke Wang, Philip Scott, Sebastian Kalt, Muamer Kadic, Martin Wegener

“…Elastic waves, i.e., phonons, in metamaterials serve as an example. We show that, in the complex plane, the Cauchy-Riemann equations for analytical functions connect the minima of the phonon band structure to frozen evanescent phonons. …”

Hybrid magnon-phonon crystals by Liyang Liao, Jiacheng Liu, Jorge Puebla, Qiming Shao, Yoshichika Otani

“…Recent advance in magnon-phonon coupling shined a light on combining magnonic and phononic crystals as hybrid magnon-phonon crystals, benefit from the tunable magnon-phonon coupling, the time-reversal symmetry breaking of magnons, and the long lifetime of phonons. …”

Nanoscale confinement of phonon flow and heat transport by Albert Beardo, Weinan Chen, Brendan McBennett, Tara Karimzadeh Sabet, Emma E. Nelson, Theodore H. Culman, Henry C. Kapteyn, Joshua L. Knobloch, Margaret M. Murnane, Ismaila Dabo

“…We examine these methods in light of experiments and atomistic calculations of heat fluxes and temperature profiles in phononic systems with nanometer-sized features. We argue that reconciling the hydrodynamic and ballistic formulations is an outstanding necessity to develop a unifying theory of confinement effects on phonon flow, which will ultimately lead to optimal strategies for thermal management in nanodevices.…”
