Three-dimensional acoustic Chern insulators with arbitrary Chern vectors

Three-dimensional acoustic Chern insulators with arbitrary Chern vectors

The Chern vector is a vectorial generalization of the scalar Chern number, being able to characterize the topological phases of three-dimensional (3D) Chern insulators. Such a vectorial generalization extends the applicability of Chern-type bulk-boundary correspondence from one-dimensional edge stat...
