Non-equilibrium dynamics of hard spheres in the fluid, crystalline, and glassy regimes

We investigate the response of a system of hard spheres to two classes of perturbations over a range of densities spanning the fluid, crystalline, and glassy regimes within a molecular dynamics framework. First, we consider the relaxation of a “thermal inhomogeneity,” in which a central region of particles is given a higher temperature than its surroundings and is then allowed to evolve under Newtonian dynamics. In this case, the hot central “core” of particles expands and collides with the cold surrounding material, creating a transient radially expanding “compression wave,” which is rapidly dissipated by particle-particle collisions and interactions with periodic images at the boundary, leading to a rapid relaxation to equilibrium. Second, we consider a rapid compression of the spheres into a disordered glassy state at high densities. Such rapidly compressed systems exhibit very slow structural relaxation times, many orders of magnitude longer than thermalization times for simple temp..., , # Data from: Non-equilibrium dynamics of hard spheres in the fluid, crystalline, and glassy regimes

## Description of the data and file structure

Data were prepared from molecular dynamic simulations of hard spheres. All datasets are included to reproduce the 12 figures in the manuscript \"Non-Equilibrium Dynamics of Hard Spheres in the Fluid, Crystalline, and Glassy Regimes\" by Kafker et al., accepted for publication in *Physical Review E*. File names contain the relevant quantities, including the figure to which the data belongs. If a figure contains an inset, the word inset is included in the file name. All files are text files. The relationship between the contents of the figures and the contents of the files will be obvious, but are also listed below for completeness.
