Three-dimensional topological acoustic crystals with pseudospin-valley coupled saddle surface states

Valley states can be used to realise topologically protected transport. Here, He et al. show that considering additional degrees of freedom, together with glide symmetry, allow the design of 2D acoustic topological pseudospin-valley coupled saddle surface states in 3D structures.
