Nonreciprocal control and cooling of phonon modes in an optomechanical system
A cavity optomechanical scheme produces robust nonreciprocal coupling between phononic resonators and is used to control the resonators’ thermal fluctuations.

Observation of a phononic quadrupole topological insulator
A two-dimensional phononic quadrupole topological insulator is demonstrated experimentally using mechanical metamaterials, which has both the one-dimensional edge states and the zero-dimensional corner states predicted by theory.

Negative refractive index and acoustic superlens from multiple scattering in single negative metamaterials
A negative refractive index, a property that does not exist in natural materials, can be produced in so-called metamaterials by combining two building blocks; here it is shown that it is possible to design and fabricate a metamaterial with a negative refractive index that consists of only one type of building block by taking advantage of its crystalline structure, and this approach is demonstrated through an acoustic superlens.
