Topological mechanics can realize soft modes in mechanical metamaterials inwhich the number of degrees of freedom for particle motion is finely balancedby the constraints provided by interparticle interactions. However, solidobjects are generally hyperstatic (or overconstrained). Here, we show howsymmetries may be applied to generate topological soft modes even inoverconstrained, rigid systems. To do so, we consider non-Hermitian topologybased on non-square matrices, and design a hyperstatic material in whichlow-energy modes protected by topology and symmetry appear at interfaces. Ourapproach presents a novel way of generating softness in robust scale-freearchitectures suitable for miniaturization to the nanoscale.
