In this manuscript we report theoretical aspects and experimental tests of topological pumping in spatially modulated plates. We show that topological edge modes are supported at one of the boundaries, depending on the modulation phase. When this parameter is adiabatically varied along the second dimension, the edge state transforms from being left to right localized (or vice-versa), therefore pumping energy from one edge to the other.

Abstract
In this manuscript we report theoretical aspects and experimental tests of topological pumping in spatially modulated plates. We show that topological edge modes are supported at one of the boundaries, depending on the modulation phase. When this parameter is adiabatically varied along the second dimension, the edge state transforms from being left to right localized (or vice-versa), therefore pumping energy from one edge to the other.File in questo prodotto:
