To monitor structural properties as a function of temperature during melt-quenching, such as the radial distribution function (RDF) plotted on Figure , we opted for subsequent steps of temperature ramp up of 100 K at 5 K/ps and plateaux of 20 ps. Shown on Figure , this succession of steps is equivalent to effective heating and cooling rates of 2.5 K/ps. We checked that the presence or absence of plateaux (with the same effective rate) has no influence on the final glasses properties, as expected for a quasistatic simulation. We also checked, and demonstrate on Figure , that in the 1.25 -5 K/ps range, the precise value does not significantly change the outcome of the simulation. We note here again that meltquenching simulations were performed in the (N, P, T ) ensemble with an isotropic cell, as the use of a flexible cell led to an undesirable fast density increase in the first tens of picoseconds, which affects the final properties of the melt-quenched glass.
