Abstract
The heterogeneous features of the supercooled state over different time regimes are explored in a self-consistent mode-coupling mode. The exponent a for the mean-square displacement (r2(t))~ta, of a tagged particle is computed. The non-Gaussian parameter α 2(t) shows a peak in the short time regime in addition to a second peak over longer times. The position of the short-time peak in α 2(t) hardly shifts, while that of the other grows with density.
