Single-particle limit of a topological edge state in a locally resonant band gap
Garigipati Sai Srikanth, Kai Qian, Ian Frankel +3
Topological metamaterials promise unprecedented wave control. Here, we theoretically and numerically investigate a one-dimensional Su-Schrieffer-Heeger (SSH)-inspired stiffness dim…
Wave propagation in an elastic lattice with non-reciprocal stiffness and engineered damping
Harshit Kumar Sandhu, Saurav Dutta, Rajesh Chaunsali
Nonreciprocal wave propagation allows for directional energy transport. In this work, we systematically investigate wave dynamics in an elastic lattice that combines nonreciprocal…
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…
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…
Gradient-index granular crystals: From boomerang motion to asymmetric transmission of waves
Eunho Kim, Rajesh Chaunsali, Jinkyu Yang
We present a gradient-index crystal that offers extreme tunability in terms of manipulating the propagation of elastic waves. For small-amplitude excitations, we achieve control ov…
