Abstract
We examine the possibility of detecting mode-coupling -correlator behaviour in the time dependence of correlation functions of supercooled liquids. We compare the theoretical scaling predictions with several translational and rotational correlation functions calculated from molecular dynamics trajectories as well as with correlation functions evaluated by solving the mode-coupling equations for hard spheres. We find that while the ideal glass transition point can be unambiguously determined by studying the evolution of correlators on approaching the glass point, the pure -correlator dynamics is hardly measurable. Information on the -scaling is important for a proper determination of the MCT critical exponents.
