Icosahedral order in metallic glasses and quasi-crystals

These papers describe the statistical mechanics of local clusters with icosahedral symmetry in supercoooled metals. The structure factor of such metals was computed, and a simple computation for the location of the peaks in the structure factor was provided. These predictions have been successfully compared with experiments (T. Schenk et al., Phys. Rev. Lett. 89, 075507 (2002) and K. F. Kelton et al., Phys. Rev. Lett. 90, 195504 (2003)). This work was highlighted in the article by Charles Day, Physics Today, 56, July 2003, page 24, and featured on the cover of this issue.
