Topological state transfer in Kresling origami
Yasuhiro Miyazawa, Chun-Wei Chen, Rajesh Chaunsali +4
Topological mechanical metamaterials have been widely explored for their boundary states, which can be robustly isolated or transported in a controlled manner. However, such system…
Corner states in second-order mechanical topological insulator
Chun-Wei Chen, Rajesh Chaunsali, Johan Christensen +2
We numerically and experimentally study corner states in a continuous elastic plate with em-bedded bolts in a hexagonal pattern. While preserving C6 crystalline symmetry, the syste…
Spin-1 Weyl Point and Surface Arc State in a Chiral Phononic Crystal
Xiaotian Shi, Jinkyu Yang
Spin-1 Weyl point is formed by three bands touching at a single point in the three dimensional (3D) momentum space, with two of which show cone-like dispersion while the third band…
Mechanical analogue of a Majorana bound state
Chun-Wei Chen, Natalia Lera, Rajesh Chaunsali +5
The discovery of topologically non-trivial electronic systems has opened a new age in condensed matter research. From topological insulators to topological superconductors and Weyl…
Experimental demonstration of topological waveguiding in elastic plates with local resonators
Rajesh Chaunsali, Chun-Wei Chen, Jinkyu Yang
It is recent that the emergence of topological insulators in condensed matter physics has inspired analogous wave phenomena in mechanical systems, mostly in the setting of discrete…
Elastic Wannier-Stark Ladders and Bloch Oscillations in 1D Granular Crystals
Xiaotian Shi, Rajesh Chaunsali, Ying Wu +1
We report the numerical and experimental study of elastic Wannier-Stark Ladders and Bloch Oscillations in a tunable one-dimensional granular chain consisting of cylindrical particl…
Dial-in Topological Metamaterials Based on Bistable Stewart Platform
Ying Wu, Rajesh Chaunsali, Hiromi Yasuda +2
Recently, there have been significant efforts to guide mechanical energy in structures by relying on a novel topological framework popularized by the discovery of topological insul…
Subwavelength and directional control of flexural waves in zone-folding induced topological plates
Rajesh Chaunsali, Chun-Wei Chen, Jinkyu Yang
Inspired by the quantum spin Hall effect shown by topological insulators, we propose a plate structure that can be used to demonstrate the pseudo-spin Hall effect for flexural wave…
Origami-based tunable truss structures for non-volatile mechanical memory operation
Hiromi Yasuda, Tomohiro Tachi, Mia Lee +1
Origami has recently received significant interest from the scientific community as a building block for constructing metamaterials. However, the primary focus has been placed on t…
