The Josephson equations predict remarkable effects concerning the phase state of a superconducting junction with an oscillating current induced by static voltage. Whether paradigm can be twisted yielding voltage without making use harmonic drives is fundamentally relevant problem yet not fully settled. Here, we demonstrate that dynamical regime evolution general hallmark driven systems exhibiti...

We study the three-dimensional equilibrium shape of a shell formed by deployed accordion-like origami, made from an elastic sheet decorated series parallel creases crossed central longitudinal crease. Surprisingly, while imprinted crease network does not exhibit geodesic curvature, emergent folded structure stemming mechanical yields angles at vertices between sections fold, producing effective...
