Active microphase separation in mixtures of microtubules and tip-accumulating molecular motors
Bezia Lemma, Noah P. Mitchell, Radhika Subramanian +2
Mixtures of microtubules and molecular motors form active materials with diverse dynamical behaviors that vary based on their constituents' molecular properties. We map the non-equ…
Origin and localization of topological band gaps in gyroscopic metamaterials
Noah P. Mitchell, Ari M. Turner, William T. M. Irvine
Networks of interacting gyroscopes have proven to be versatile structures for understanding and harnessing finite-frequency topological excitations. Spinning components give rise t…
Conforming nanoparticle sheets to surfaces with Gaussian curvature
Noah P. Mitchell, Remington L. Carey, Jelani Hannah +5
Nanoparticle monolayer sheets are ultrathin inorganic-organic hybrid materials that combine highly controllable optical and electrical properties with mechanical flexibility and re…
Tunable Band Topology in Gyroscopic Lattices
Noah P. Mitchell, Lisa M. Nash, William T. M. Irvine
Gyroscopic metamaterials --- mechanical structures composed of interacting spinning tops --- have recently been found to support one-way topological edge excitations. In these stru…
