Topological Phase Transition in Mechanical Honeycomb Lattice
Yi Chen, Xiaoning Liu, Gengkai Hu
Topological materials provide a new tool to direct wave energy with unprecedented precision and robustness. Three elastic topological phases, the valley Hall, Chern and spin Hall i…
Extremal micropolar materials for elastic wave cloaking
Dingxin Sun, Yi Chen, Xiaoning Liu +1
The asymmetric transformation elasticity offers a promising method to control elastic waves. However, this method requires elastic materials that support asymmetric stresses, which…
Rayleigh surface waves of extremal elastic materials
Yu Wei, Yi Chen, Wen Cheng +2
Extremal elastic materials here refer to a specific class of elastic materials whose elastic matrices exhibit one or more zero eigenvalues, resulting in soft deformation modes that…
Chiral Triclinic Metamaterial Crystals Supporting Isotropic Acoustical Activity and Isotropic Chiral Phonons
Yi Chen, Muamer Kadic, Martin Wegener
Recent work predicted the existence of isotropic chiral phonon dispersion relations of the lowest bands connected to isotropic acoustical activity in cubic crystalline approximants…
High-Frequency Gravitational-Wave Detection Using a Chiral Resonant Mechanical Element and a Short Unstable Optical Cavity
Yi Chen, Muamer Kadic, David E. Kaplan +3
Present gravitational wave detectors are based on the measurement of linear displacement in stable optical cavities. Here, we instead suggest the measurement of the twist of a chir…
An asymmetric elastic metamaterial model for elastic wave cloaking
Hongkuan Zhang, Yi Chen, Xiaoning Liu +1
Elastic material with its elastic tensor losing minor symmetry is considered impossible without introducing artificially body torque. Here we demonstrate the feasibility of such ma…
