Predictive beam-lattice reduction for higher-order topological modes in a 2D SSH phononic crystal
Eloi Perez Compte, Michele Brun, Giorgio Carta +3
We develop a mechanically faithful reduced model for a two-dimensional topological phononic crystal composed of rigid square masses connected by slender elastic ligaments. Exploiti…

Tunable topological edge modes in Su-Schrieffer-Heeger arrays
G. J. Chaplain, A. S. Gliozzi, B. Davies +4
A potential weakness of topological waveguides is that they act on a fixed narrow band of frequencies. However, by 3D printing samples from a photo-responsive polymer, we can obtai…
