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…
Realization of a Topological Phase Transition in a Gyroscopic Lattice
Noah P. Mitchell, Lisa M. Nash, William T. M. Irvine
Topological metamaterials exhibit unusual behaviors at their boundaries, such as unidirectional chiral waves, that are protected by a topological feature of their band structure. T…
Amorphous topological insulators constructed from random point sets
Noah P. Mitchell, Lisa M. Nash, Daniel Hexner +2
The discovery that the band structure of electronic insulators may be topologically non-trivial has unveiled distinct phases of electronic matter with novel properties. Recently, m…
