Hyperuniformity characterizes a state of matter for which (scaled) density fluctuations diminish towards zero at the largest length scales. However, the task of determining whether or not an image of an experimental system is hyperuniform is experimentally challenging due to finite-resolution, noise, and sample-size effects that influence characterization measurements. Here we explore these issues, employing video optical microscopy to study hyperuniformity phenomena in disordered two… 
Methodology to construct large realizations of perfectly hyperuniform disordered packings.
TLDR
It is proved that the constructed packings with a polydispersity in size are perfectly hyperuniform in the infinite-sample-size limit, regardless of particle shapes, positions, and numbers per cell.
Disordered hyperuniformity in two-dimensional amorphous silica
TLDR
It is shown via large-scale density functional theory calculations that DHU leads to almost complete closure of the electronic bandgap compared to the crystalline counterpart, making the material effectively a metal, in contrast to the conventional wisdom that disorder generally diminishes electronic transport.
Transport, geometrical, and topological properties of stealthy disordered hyperuniform two-phase systems.
TLDR
As the extent of short-range order increases, stealthy disordered two-phase media can attain nearly maximal effective diffusion coefficients over a broad range of volume fractions while also maintaining isotropy, and therefore may have practical applications in situations where ease of transport is desirable.
Hyperuniformity and its generalizations.
TLDR
It is shown that there exist many-particle ground-state configurations in which directional hyperuniformity imparts exotic anisotropic physical properties to these states of matter, which could have technological relevance for manipulating light and sound waves in ways heretofore not thought possible.
Structural characterization of many-particle systems on approach to hyperuniform states.
TLDR
The focus of this work is the exploration of quantitative descriptors that herald when a many-particle system in d-dimensional Euclidean space R^{d} approaches a hyperuniform state as a function of the relevant control parameter.
Enhanced Pinning For Vortices in Hyperuniform Substrates and Emergent Hyperuniform Vortex States
Disordered hyperuniformity is a state of matter which has isotropic liquid like properties while simultaneously having crystalline like properties such as little variation in the density fluctuations
Effect of Window Shape on the Detection of Hyperuniformity via the Local Number Variance
Hyperuniform many particle systems in d-dimensional space, which includes crystals, quasicrystals, and some exotic disordered systems, are characterized by an anomalous suppression of density

TLDR
New rigorous criteria that disordered hyperuniform two-phase heterogeneous materials must obey are derived and implications for the design of such novel amorphous materials are explored.
Microstructure and mechanical properties of hyperuniform heterogeneous materials.
TLDR
A stochastic optimization procedure is employed to systematically generate realizations of hyperuniform heterogeneous materials with controllable short-range order, which is partially quantified using the two-point correlation function S_{2}(r) associated with the phase of interest.
Multifunctional hyperuniform cellular networks: optimality, anisotropy and disorder
Disordered hyperuniform heterogeneous materials are new, exotic amorphous states of matter that behave like crystals in the manner in which they suppress volume-fraction fluctuations at large length
