Abstract
We present results of large-scale molecular dynamics simulations of hard sphere systems at values of the volume fraction along the disordered, metastable branch of the phase diagram up to random close-packing . By quantifying the degree of local order, we determine the necessary conditions to obtain a truly random system, enabling us to compute the pressure carefully along the entire metastable branch. Near we show that the pressure scales as , where and . Contrary to previous studies, we find no evidence of a thermodynamic glass transition and find that after long times the system crystallizes for all above the melting point.
