Au. x. system hosts the first known example of an elastic quantum critical point. Neutron and x-ray diffraction measurements were performed to study the structural properties as a function of temperature and Au-composition. First principle calculations confirm that the phase transition is driven by an elastic instability and is independent of electronic properties. Heat capacity measurements indicate the presence of quantum fluctuations at the critical composition. . CD/DVD drive. Image top. : . http://en.wikipedia.org/wiki/File:Dismdvd.. jpg.
