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…
Deformation insensitive thermal conductance of the designed Si metamaterial
Lina Yang, Quan Zhang, Gengkai Hu +1
The thermal management have been widely focused due to broad applications. Generally, the deformation can largely tune the thermal transport. The main challenge of flexible electro…
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…
Boundary effect on acoustic cloak with unideal pentamode material
Yi Chen, Xiaoning Liu, Gengkai Hu
Pentamode materials are elastic solids with vanishing shear modulus, and can be used cloak underwater sound with solid state and broadband merits. However, pentamode materials real…
Elastic quantum spin-Hall effect in Kagome lattices
Hui Chen, Hussein Nassar, Andrew N. Norris +2
A Quantum Spin-Hall Insulator (QSHI) is implemented into a simple mass-spring Kagome lattice. The transition from the trivial state to the topological one is described by an invari…
