Observation of a topological nodal surface and its surface-state arcs in an artificial acoustic crystal
Here, the authors report on the experimental observation of a twofold symmetry enforced topological nodal surface in a 3D chiral acoustic crystal. The demonstrated nodal surface carries a topological charge of 2, constituting the first realization of higher-dimensional topologically-charged band deg...

| Sumario: | Here, the authors report on the experimental observation of a twofold symmetry enforced topological nodal surface in a 3D chiral acoustic crystal. The demonstrated nodal surface carries a topological charge of 2, constituting the first realization of higher-dimensional topologically-charged band degeneracy. |
