abstract

• Upon compression, the equilibrium hard-sphere liquid [pair potential uHS(r)] freezes at a packing fraction ηf = 0.494 or, if crystallization is prevented, becomes metastable up to its glass transition at φg ≈ 0.58. Throughout the fluid regime (φ < φg), we are, thus, certain that this model liquid does not exhibit any form of kinetic arrest. If, however, a small portion of these spheres (packing fraction φ2 ≈ φ) happen to ignore each other [u22(r) = 0] but do not ignore the remaining normal hard spheres [u12(r) = u21(r) = u11(r) = uHS(r)], whose packing fraction is thus φ1 = φ - φ2, they run the risk of becoming dynamically arrested before they demix from the normal particles. This unexpected and counterintuitive scenario was first theoretically predicted and then confirmed by simulations. © 2018 Author(s).
