Making the cut: lattice kirigami rules

Phys Rev Lett. 2014 Dec 12;113(24):245502. doi: 10.1103/PhysRevLett.113.245502. Epub 2014 Dec 11.


In this Letter we explore and develop a simple set of rules that apply to cutting, pasting, and folding honeycomb lattices. We consider origami-like structures that are extrinsically flat away from zero-dimensional sources of Gaussian curvature and one-dimensional sources of mean curvature, and our cutting and pasting rules maintain the intrinsic bond lengths on both the lattice and its dual lattice. We find that a small set of rules is allowed providing a framework for exploring and building kirigami—folding, cutting, and pasting the edges of paper.
