Topological mechanics of gyroscopic metamaterials
Lisa M. Nash, Dustin Kleckner, Alismari Read +3
Topological mechanical metamaterials are artificial structures whose unusual properties are protected very much like their electronic and optical counterparts. Here, we present an…
Solitons and thermal fluctuations in strongly nonlinear solids
N. Upadhyaya, A. M. Turner, V. Vitelli
We study a chain of anharmonic springs with tunable power law interactions as a minimal model to explore the propagation of strongly non-linear solitary wave excitations in a backg…
Uniform Shock Waves in Disordered Granular Matter
L. R. Gomez, A. M. Turner, V. Vitelli
The confining pressure is perhaps the most important parameter controlling the properties of granular matter. Strongly compressed granular media are, in many respects, simple s…
Shocks near Jamming
Leopoldo R. Gomez, Ari M. Turner, Martin van Hecke +1
Non-linear sound is an extreme phenomenon typically observed in solids after violent explosions. But granular media are different. Right when they jam, these fragile and disordered…
Vortices in Superfluid Films on Curved Surfaces
Ari M. Turner, Vincenzo Vitelli, David R. Nelson
We present a systematic study of how vortices in superfluid films interact with the spatially varying Gaussian curvature of the underlying substrate. The Gaussian curvature acts as…
Anomalous coupling between topological defects and curvature
Vincenzo Vitelli, Ari Turner
We investigate a counterintuitive geometric interaction between defects and curvature in thin layers of superfluids, superconductors and liquid crystals deposited on curved surface…
