DESCRIPTION:It is not generally expected that systems described by simple 
 pair potentials show complex phase behaviour. The Jagla matter\, a hard-sp
 here system augmented by a linear attraction term\, has been used to study
  liquid-liquid transition\, but its solid phases have been assumed to form
  simple close-packed crystals. In my talk I will present how we used neste
 d sampling to discover some thermodynamically stable\, but structurally ex
 otic phases that are far from close packed. Even more striking are the sim
 ilarities between the new Jagla phase and ice VI\, a high-pressure polymor
 ph of water.
