The study of classical wave physics has been reinvigorated by incorporating the concept of
the geometric phase, which has its roots in optics, and topological notions that were …

Depending on the geometry of their Fermi surfaces, Weyl semimetals and their analogs in
classical systems have been classified into two types. In type-I Weyl semimetals (WSMs), the …

The study of Weyl points in electronic systems has inspired much recent research in
classical systems such as photonic and acoustic lattices. Here we show how Weyl physics …

Acoustic metamaterials are a class of artificially periodic structures with extraordinary elastic
properties that cannot be easily found in naturally occurring materials and can be applied to …

Topological mechanical metamaterials have emerged as an active research field with the
rapid development of topological phases in condensed matter physics. By incorporating …
