    • note
    • For a given number of particles W and a given volume V, hence a given density ρ=N/V, the potential-energy landscape, i.e., the hypersurface of potential energy plotted as a function of the 3 N configurational coordinates, is independent of temperature.

    • note
    • It is likely that for such strongly interacting glassformers temperature is the dominant driving parameter of the viscous slowing down so long as pressure does not change the local structure of the liquid.

    • note
    • Note that, in the range of temperature accessible to our computer simulations, there is no significant decoupling between the translational diffusion constant and the other relaxation times.

    • note
    • An excess thermodynamic quantity is defined here as the contribution due to the interactions that cornes on top of an ideal-gas result.

    • note
    • This, as well as the results in Fig. 8, casts some doubts on the ability of the Lewis-Wahnström model to accurately represent liquid ortho-terphenyl.
