"Analytical description of amorphous
solid structures"

Recent experimental, computational and
theoretical results suggest a strong link
between amorphous precursor mediated
crystal nucleation and the glass transition.
The first step in exploring this link is the
analytical description of bulk amorphous
structures. Recent numerical results suggest,
that this should be possible in the framework
of continuum theories providing unstructured
solutions (these represent the amorphous phase).
I will show, that the associated energy density
functionals might have continuum infinitely many
extrema in the infinite volume limit. These
extrema can be generated according to a
continuous probability measure, yet representing
a unique energy density. The key to a stochastic
solution of a deterministic PDE is Isserlis'
Theorem, that guarantees the convergence of the
energy density in the infinite volume limit for
coloured Gaussian noise.
