Fig. 5: Geometry of the eigenmodes shapes plasticity.
a Spatial correlation functions between plastic events at strain γ = 0.01 and topological defects with positive charge (black curve) and negative charge (red curve) for different frequencies. The PEs result from a shear in the xy-plane. b The maximum of g-PE(r; ω) as a function of ω. c Weighted sums over ω of g−PE(r; ω) and g+PE(r; ω), left and right panel, respectively, for four different strains γ. The weights are ω−2 and all modes in the range 0.6 < ω < 1.29 have been taken into account. Curves are shifted downwards by multiples of 0.2 for the sake of visibility. d A 3D view of the isosurface of the smoothed charge density field Ω(R) with a iso-level value of − 1.25 ⋅ 10−4. Note the presence of large holes in the structure, which represent zones of little plastic activity. e Two slices to show the spatial correlation between PE (white spheres) and regions with larger negative TD charge density. The colorbar range is from − 1.25 ⋅ 10−4 (blue) to 1.25 ⋅ 10−4 (red).
