Topological mechanics of origami and kirigami
Bryan Gin-ge Chen, Bin Liu, Arthur A. Evans +4
Origami and kirigami have emerged as potential tools for the design of mechanical metamaterials whose properties such as curvature, Poisson ratio, and existence of metastable state…
At the end of a moving string
J. A. Hanna, C. D. Santangelo
One cannot pull an open, curved string along itself. This fact is clearly reflected in the unwrapping motion of a string or chain as it is dragged around an object, and implies str…
Packing Squares in a Torus
Don Blair, Christian D. Santangelo, Jon Machta
The densest packings of N unit squares in a torus are studied using analytical methods as well as simulated annealing. A rich array of dense packing solutions are found: density-on…
Undulated cylinders of charged diblock copolymers
Gregory M. Grason, Christian D. Santangelo
We study the cylinder to sphere morphological transition of diblock copolymers in aqueous solution with a hydrophobic block and a charged block. We find a metastable undulated cyli…
Effects of counterion fluctuations in a polyelectrolyte brush
C. D. Santangelo, A. W. C. Lau
We investigate the effect of counterion fluctuations in a single polyelectrolyte brush in the absence of added salt by systematically expanding the counterion free energy about Poi…
Coiling Instabilities in Multilamellar Tubes
C. D. Santangelo, P. Pincus
Myelin figures are densely packed stacks of coaxial cylindrical bilayers that are unstable to the formation of coils or double helices. These myelin figures appear to have no intri…
