Significance An ongoing challenge in modern materials science is to create artificial structures, termed metamaterials, with an unconventional response that can be programmed by suitable design of their geometry or topology. We demonstrate a novel metamaterial in which small structural variations single out regions that buckle selectively under external stresses. Surprisingly, these regions are at first glance indistinguishable from the rest of the structure. Our samples are examples of…

Nonlinear conduction via solitons in a topological mechanical insulator
This work builds a topologically protected mechanism that can perform basic tasks such as transporting a mechanical state from one location to another and paves the way toward adopting the principle of topological robustness in the design of robots assembled from activated linkages as well as in the fabrication of complex molecular nanostructures.
Surface phonons, elastic response, and conformal invariance in twisted kagome lattices
Elasticity and phonons of a special class of two-dimensional isostatic lattices constructed by distorting the kagome lattice are explored and it is shown that the phonon structure of these lattices, characterized by vanishing bulk moduli and thus negative Poisson ratios, depends sensitively on boundary conditions and on the nature of the k Kagome distortions.
