Calorimetric glass transition explained by hierarchical dynamic facilitation
Aaron S. Keys, Juan P. Garrahan, David Chandler
The glass transition refers to the non-equilibrium process by which an equilibrium liquid is transformed to a non-equilibrium disordered solid, or vice versa. Associated response f…
Self Assembly of Soft Matter Quasicrystals and Their Approximants
Christopher R. Iacovella, Aaron S. Keys, Sharon C. Glotzer
The surprising recent discoveries of quasicrystals and their approximants in soft matter systems poses the intriguing possibility that these structures can be realized in a broad r…
Disordered, Quasicrystalline and Crystalline Phases of Densely Packed Tetrahedra
Amir Haji-Akbari, Michael Engel, Aaron S. Keys +4
All hard, convex shapes are conjectured by Ulam to pack more densely than spheres, which have a maximum packing fraction of ϕ = π/\sqrt18 ~ 0.7405. For many shapes, simple lattice…
Measurement of Growing Dynamical Lengthscales and Prediction of the Jamming Transition in a Granular Material
Aaron S. Keys, Adam R. Abate, Sharon C. Glotzer +1
Supercooled liquids and dense colloids exhibit anomalous behaviour known as "spatially heterogeneous dynamics" (SHD), which becomes increasingly pronounced with approach to the gla…
Harmonic Order Parameters for Characterizing Complex Particle Morphologies
Aaron S. Keys, Christopher R. Iacovella, Sharon C. Glotzer
Order parameters based on spherical harmonics and Fourier coefficients already play a significant role in condensed matter research in the context of systems of spherical or point…
Characterizing Structure Through Shape Matching and Applications to Self Assembly
Aaron S. Keys, Christopher R. Iacovella, Sharon C. Glotzer
Structural quantities such as order parameters and correlation functions are often employed to gain insight into the physical behavior and properties of condensed matter systems. W…
