The topological properties of an object, associated with an integer called the topological
invariant, are global features that cannot change continuously but only through abrupt …

High quality nanomechanical oscillators are promising platforms for quantum entanglement
and quantum technology with phonons. Realizing coherent transfer of phonons between …

Breaking acoustic reciprocity is essential to create robust one-way propagation where sound
waves or elastic vibrations are permitted to travel in only one direction. This unidirectional …

The distinction and correlation between intrinsic and boundary-induced properties represent
a core problem in material physics. While resonant modes do not exist within band gaps in …

Topological mechanical metamaterials have been widely explored for their boundary states,
which can be robustly isolated or transported in a controlled manner. However, such …

We propose several schemes with diverse optional types of couplings to accelerate
adiabatic topological quantum state transfers (QSTs) in optomechanical lattices (OMLs) by …

The temporal modulation of a relevant parameter can be employed to induce modal
transformations in Hermitian elastic lattices. When this is combined with a proper excitation …

We propose to implement fast and robust quantum state transfer in symmetrical beam
splitters and routers through a specific topological edge channel in splicing Su-Schrieffer …
