From: Heterogeneous shear elasticity of glasses: the origin of the boson peak
Histogram of the 6 eigenvalues Ci of the Kelvin stiffness tensor Cij evaluated using Born's force constants for a tiling of the total volume into 573 boxes (Vc = 44, red dashes) and into 163 boxes (Vc = 2000, blue lines).
The total volume is V = 8.3 · 106. Insert: Mean values 〈Ci〉 (top group) and disorder parameters 
(bottom group) vs. coarse-graining volume Vc. The top and bottom black lines correspond to 
, the others to 
.
