Vortex states in an acoustic Weyl crystal with a topological lattice defect
Vortex states in an acoustic Weyl crystal with a topological lattice defect
Crystalline materials can host topological lattice defects that are robust against local deformations, and such defects can interact in interesting ways with the topological features of the underlying band structure. We design and implement a three dimensional acoustic Weyl metamaterial hosting robust modes bound to a one-dimensional topological lattice defect. …
