Role of nonlinearities in topological protection: Testing magnetically coupled fidget spinners
Role of nonlinearities in topological protection: Testing magnetically coupled fidget spinners
We investigate and experimentally observe the existence of topologically protected interface modes in a one-dimensional mechanical lattice, and we report on the effect of nonlinearities on topological protection. The lattice consists of a one-dimensional array of spinners with nearest neighbor coupling resulting from magnetic interactions. The distance between the spinners …
