Query: Evidence of a one-dimensional thermodynamic phase diagram for simple
  glass-formers   The glass transition plays a central role in nature as well as in industry,
ranging from biological systems such as proteins and DNA to polymers and
metals. Yet the fundamental understanding of the glass transition which is a
prerequisite for optimized application of glass formers is still lacking. Glass
formers show motional processes over an extremely broad range of timescales,
covering more than ten orders of magnitude, meaning that a full understanding
of the glass transition needs to comprise this tremendous range in timescales.
Here we report on first-time simultaneous neutron and dielectric spectroscopy
investigations of three glass-forming liquids, probing in a single experiment
the full range of dynamics. For two van der Waals liquids we locate in the
pressure-temperature phase diagram lines of identical dynamics of the molecules
on both second and picosecond timescales. This confirms predictions of the
isomorph theory and effectively reduces the phase diagram from two to one
dimension. The implication is that dynamics on widely different timescales are
governed by the same underlying mechanisms.
