ATOMIC DANCE DRIVES MELTING
Melting is probably the most familiar phase transition, but researchers
still don't agree on exactly how an idealized, perfect solid becomes
liquid. In the April Physical Review B, researchers describe the atomic
choreography that accompanies this process in a computer version of
a crystal. They attribute melting to increasingly complex motions of
groups of atoms acting in concert, rather than to vibrations of individual
atoms or to particular atomic arrangements invoked by previous
researchers.
(Xian-Ming Bai and Mo Li, Phys. Rev. B 77, 134109)
