Query: Excess Vibrational Density of States and the Brittle to Ductile
  Transition in Crystalline and Amorphous Solids   The conditions which determine whether a material behaves in a brittle or
ductile fashion on mechanical loading are still elusive and comprise a topic of
active research among materials physicists and engineers. In this study, we
present results of {\em in silico} mechanical deformation experiments from two
very different model solids in two and three dimensions. The first consists of
particles interacting with isotropic potentials and the other has strongly
direction dependent interactions. We show that in both cases, the excess
vibrational density of states is the fundamental quantity which characterises
the ductility of the material. Our results can be checked using careful
experiments on colloidal solids.
