We report a molecular dynamics simulation of a supercooled simple monatomicglass-forming liquid. It is found that the onset of the supercooled regimeresults in formation of distinct domains of slow diffusion which are confinedto the long-lived icosahedrally structured clusters associated with deeperminima in the energy landscape. As these domains, possessing a low-dimensionalgeometry, grow with cooling and percolate below $T_c$, the critical temperatureof the mode coupling theory, a sharp slowing down of the structural relaxationrelative to diffusion is observed. It is concluded that this latter anomalycannot be accounted for by the spatial variation in atomic mobility; instead,we explain it as a direct result of the configuration-space constraints imposedby the transient structural correlations. We also conjecture that the observedtendency for low-dimensional clustering may be regarded as a possible mechanismof fragility.Comment: To be published in PR
