Abstract

By means of computer simulations we investigate the dynamical behavior of a binary lattice-gas mixture with short-range interactions in order to provide a stringent test of mode-coupling theory (MCT). The dynamics of the particles is given by Monte Carlo-like moves that change the positions of the particles and binary collisions that change the velocities. By monitoring the self part of the van Hove correlation function we find the low-temperature dynamics to be glasslike. In accordance with MCT, the imaginary part of the dynamic susceptibility χ'' shows a well-defined α peak whose high frequency wing follows a von Schweidler law with an exponent that is independent of temperature
