@article{Cha2018ExperimentalRO, title={Experimental realization of on-chip topological nanoelectromechanical metamaterials}, author={Jinwoong Cha and Kun Woo Kim and Chiara Daraio}, journal={Nature}, year={2018}, volume={564}, pages={229-233} }

Guiding waves through a stable physical channel is essential for reliable information transport. However, energy transport in high-frequency mechanical systems, such as in signal-processing applications1, is particularly sensitive to defects and sharp turns because of back-scattering and losses2. Topological phenomena in condensed matter systems have shown immunity to defects and unidirectional energy propagation3. Topological mechanical metamaterials translate these properties into classical… Expand
