‘Fivefold Symmetry in Condensed Matter: Glass formation Competes with Crystallisation’
by C. P. Royall,
School of Physics and School of Chemistry, University of Bristol.
That fivefold symmetry should play a crucial role in the non-equilibrium behaviour of condensed matter was proposed in the 1950s . Six decades later, the basic mechanism of the solidification of liquids remains unexplained, either in the case that the material crystallises, or that it forms an amorphous solid, a glass . We will explore the implications of fivefold symmetry in the solidification of liquids and discuss two recent developments.
Crystallisation is among the most common everyday physical phenomena. Yet in the only material in which quantitative comparison has been made between experiment and theory — hard spheres — predictions of crystal nucleation rates are up to 20 orders of magnitude slower…
