Topological Defects in Gravitational Lensing Shear Fields
Vincenzo Vitelli, Bhuvnesh Jain, Randall D. Kamien
Shear fields due to weak gravitational lensing have characteristic coherent patterns. We describe the topological defects in shear fields in terms of the curvature of the surface d…
Energy transport in jammed sphere packings
Ning Xu, Vincenzo Vitelli, Matthieu Wyart +2
We calculate the normal modes of vibration in jammed sphere packings to obtain the energy diffusivity, a spectral measure of transport. At the boson peak frequency, we find an Ioff…
Nematic textures in spherical shells
Vincenzo Vitelli, David R. Nelson
The equilibrium texture of nematic shells is studied as a function of their thickness. For ultrathin shells the ground state has four short 1/2 disclination lines but, as the thick…
Crystallography on Curved Surfaces
Vincenzo Vitelli, Julius B. Lucks, David R. Nelson
We study static and dynamical properties that distinguish two dimensional crystals constrained to lie on a curved substrate from their flat space counterparts. A generic mechanism…
Defect generation and deconfinement on corrugated topographies
Vincenzo Vitelli, David R. Nelson
We investigate topography-driven generation of defects in liquid crystals films coating frozen surfaces of spatially varying Gaussian curvature whose topology does not automaticall…
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…
