Topological phononic materials: Computation and data.

Considering the current volume of materials data, it is impossible to investigate each compound by trial-and-error experiments involving labor-intensive efforts. The scientists in the Shenyang National Laboratory for Materials Science developed a home-made software, HT-PHONON, selecting over 5,000 topological phononic (TP) materials out of 13,000 materials within high-throughput computational materials design combined with a big data analysis. Furthermore, an online database for TP materials has been constructed, which is now freely open to the public community through the website www.phonon.synl.ac.cn. In this perspective, we review this platform and discuss exciting consequences of TP materials that are expected from manipulating the phonons, linking fundamental research to potential applications.
