We experimentally demonstrate temporal pumping of elastic waves in an electromechanical waveguide. Temporal pumping exploits a virtual dimension mapped to time, enabling the generation and control of edge states, typical of two-dimensional systems, in a one-dimensional waveguide. We show experimentally that the temporal modulation of the stiffness drives the transfer of edge states from one boundary of the waveguide to the other. The considered implementation, that consists of an elastic…

Bandgap Engineering in Phononic Crystals and Elastic Metamaterials
In solid state physics, a bandgap (BG) refers to a range of energies where no electronic states can exist. This concept was extended to classical waves, spawning the entire fields of photonic and

Encircling exceptional points of Bloch waves: mode conversion and anomalous scattering
The normal modes of nonconservative systems coalesce at the so-called exceptional points (EPs) of their spectrum. These degeneracy points are the source of unusual phenomena, some of which are

Landau-Zener Transition in the Dynamic Transfer of Acoustic Topological States.
This work demonstrates the transfer of topological boundary states (TBSs) across the bulk to the opposite boundary in an acoustic waveguide system and unveils the quantitative condition for the breakdown of adiabaticity in the system by demonstrating the Landau-Zener transition with both theory and experiments.
Experimental Demonstration of Dynamic Topological Pumping across Incommensurate Bilayered Acoustic Metamaterials.
The first unassisted dynamic energy transfer across a metamaterial is reported, via pumping of such topological edge modes in a topological aperiodic acoustic crystal, with a phason that can be fast and periodically driven in adiabatic cycles.
