Four-point susceptibility of a glass-forming binary mixture: Brownian dynamics.
We study the four-point dynamic susceptibility chi4(t) obtained from Brownian dynamics computer simulations of the Kob-Andersen Lennard-Jones mixture. We compare the results of the simulations with qualitative predictions of the mode-coupling theory. In addition, we test an estimate of the four-point susceptibility recently proposed by Berthier [Science 310, 1797 (2005)].
