Topological and morphological signatures of disorder in a self-assembled, soft matter sponge network
Xueyang Feng, Suman S. Kulkarni, Michael S. Dimitriyev +4
Many soft matter systems exhibit ordered, polycontinuous network morphologies, such as the cubic (double) gyroid or diamond, as well as disordered network morphologies known generi…
Variations on the Three-Sphere: Laves' Labyrinth Lopped
Lauren Niu, Randall D. Kamien
Inspired by the structure of Laves networks in that underpin the celebrated gyroid surface, we construct a Laves network of identical three-coordinated vertice…
Dislocations and Fibrations: The Topological Structure of Knotted Smectic Defects
Paul G. Severino, Randall D. Kamien, Benjamin Bode
In this work, we investigate the topological properties of knotted defects in smectic liquid crystals. Our story begins with screw dislocations, whose radial surface structure can…
You Have to Grow Wefts to Fold Them
Lauren Niu, Geneviève Dion, Randall D. Kamien
Knitting turns a one dimensional yarn into a highly ramified three-dimensional structure. As a method of additive manufacturing, it holds promise for a new class of lightweight, ul…
X-ray diffraction reveals the consequences of strong deformation in thin smectic films: dilation and chevron formation
Jean de Dieu Niyonzima, Haifa Jeridi, Lamya Essaoui +14
Smectic liquid crystals can be viewed as model systems for lamellar structures for which there has been extensive theoretical development. We demonstrate that a nonlinear energy de…
A Bouquet for Apollonius: Focal Conics in Sessile Cholesteric Droplets
Randall D. Kamien, Yuriy Nastishin, Brigitte Pansu
Focal conic domains, are defects characteristic of layered liquid crystal phases. Their association can built flowers where petals are the ellipses of the Dupin cyclides involved i…
