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…
Stability of topological edge states under strong nonlinear effects
Rajesh Chaunsali, Haitao Xu, Jinkyu Yang +2
We examine the role of strong nonlinearity on the topologically-robust edge state in a one-dimensional system. We consider a chain inspired from the Su-Schrieffer-Heeger model, but…
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…
Self-induced topological transition in phononic crystals by nonlinearity management
Rajesh Chaunsali, Georgios Theocharis
A new design paradigm of topology has recently emerged to manipulate the flow of phonons. At its heart lies a topological transition to a nontrivial state with exotic properties. T…
