Abstract
We study the structure and dynamics of crystals of minimally polydisperse
hard spheres at high pressures. Structurally, they exhibit a power-law scaling
in their probability distribution of weak forces and small interparticle gaps
as well as a flat density of vibrational states. Dynamically, they display
anomalous aging beyond a characteristic pressure. Although essentially
crystalline, these solids thus display features reminiscent of the Gardner
phase observed in certain amorphous solids. Because preparing these materials
is fast and facile, they are ideal for testing a theory of amorphous materials.
They are also amenable to experimental realizations in commercially-available
particulate systems.

Professor Charbonneau studies soft matter. His work combines theory and simulation
to understand the glass problem, protein crystallization, microphase formation, and colloidal
assembly in external fields.
