Finding the ground states of identical particles packed on spheres has relevance for stabilizing emulsions and has a venerable history in the literature of theoretical physics and mathematics. Theory and experiment have confirmed that defects such as disclinations and dislocations are an intrinsic part of the ground state. Here we discuss the remarkable behavior of vacancies and interstitials in spherical crystals. The strain fields of isolated disclinations forced in by the spherical topology… Expand
Fractionalization of interstitials in curved colloidal crystals.
TLDR
This work inserts interstitials in a lattice of similar colloidal particles sitting on flat or curved oil/glycerol interfaces, and imaged the ensuing dynamics to suggest the existence of particle fractionalization on curved surface crystals. Expand
Two-dimensional matter: order, curvature and defects
Many systems in nature and the synthetic world involve ordered arrangements of units on two-dimensional surfaces. We review here the fundamental role payed by both the topology of the underlyingExpand
Relaxation of interstitials in spherical colloidal crystals
Abstract Spherical colloidal crystals (CCs) self-assemble on the interface between two liquids. These 2D structures unconventionally combine local hexagonal order and spherical geometry. Nowadays CCsExpand
Topological vacancies in spherical crystals.
TLDR
This work shows the promising potential of exploiting richness in both physical interactions and substrate geometries to create new types of crystallographic defects, which have strong connections with the design of crystalline materials. Expand
Stress driven fractionalization of vacancies in regular packings of elastic particles.
TLDR
The remarkable fractionalization of vacancies creates rich modes of interaction between vacancies and other topological defects, and provides a new dimension for mechanical engineering of defects in extensive crystalline structures. Expand
Intermittency of Deformation and the Elastic Limit of an Icosahedral Virus under Compression.
TLDR
It is found that even at small stresses, well below the yielding point and generally thought to induce a Hookean response, strain continues to develop in time via sparse, randomly distributed, relatively rapid plastic events. Expand
Problems at the Nexus of Geometry and Soft Matter: Rings, Ribbons and Shells
iv problem of two concentric rings connected via springs. We show that when the two rings loses contact, rucks spontaneous formed leading to the complex folding patterns. We also develop a simpleExpand
Reconstruction of the 3D structure of colloidosomes from a single SEM image
In this paper we show how the 3-dimensional structural arrangement of particles in a colloidosome is derived from a single scanning electron microscopy (SEM) image. We exploit the fact that particlesExpand
Elastic platonic shells.
TLDR
This work shows that by deflating a crystalline shell with defects, it is possible to create elastic shell analogs of the classical platonic solids and suggests methods to engineer shape into soft spherical shells using a frozen defect topology. Expand
Precise self-positioning of colloidal particles on liquid emulsion droplets.
TLDR
Using ligand-decorated particles, and the precise temperature-tunable surface position control found here, may also allow using these droplets for directed supra-droplets self-assembly into larger structures, with a possible post-assembly structure-fixation by UV-polymerization of the droplet's liquid.

TLDR
It is found that the centered interstitial is the lowest-energy defect for a very wide range of interactions; the symmetric vacancy is preferred only for extremely short interaction ranges. Expand
Diffusion of point defects in two-dimensional colloidal crystals
TLDR
Evidence that the excitation of point defects into dislocation pairs enhances the diffusion of di-vacancies in two-dimensional colloidal crystals is seen, and the hopping of the defects does not follow a pure random walk, but exhibits surprising memory effects. Expand

TLDR
It is shown that vacancies and interstitials, which are stable defects in flat crystals, are generally unstable in curved geometries, which explains why vacancies orInterstitials are never found in equilibrium spherical crystals. Expand

TLDR
Experimental investigations of the structure of two-dimensional spherical crystals find that crystals develop distinctive high-angle grain boundaries, or scars, not found in planar crystals above a critical system size. Expand
