Disorder-induced topological phase transition in a 1D mechanical system
Xiaotian Shi, Ioannis Kiorpelidis, Rajesh Chaunsali +3
We numerically investigate the topological phase transition induced purely by disorder in a spring-mass chain. We employ two types of disorders - chiral and random types - to explo…
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…
Elastic Weyl points and surface arc states in 3D structures
Xiaotian Shi, Rajesh Chaunsali, Feng Li +1
The study of Weyl points in electronic systems has inspired many recent researches in classical systems such as photonic and acoustic lattices. Here we show how the Weyl physics ca…
Bloch oscillation of elastic waves in the graded lattice of 3D-printed hollow elliptical cylinders
Hyunryung Kim, Xiaotian Shi, Eunho Kim +1
We study the Bloch oscillation of elastic waves in a chain composed of hollow elliptical cylinders (HECs). These HECs are 3D-printed in different wall thicknesses and are arranged…
