Non-affine fluctuations and the Statistics of Defect Precursors in the Planar Honeycomb Lattice
Amartya Mitra, Saswati Ganguly, Surajit Sengupta +1
Certain localised displacement fluctuations in the planar honeycomb lattice may be identified as precursors to topological defects. We show that these fluctuations are among the mo…

Statistics of non-affine defect precursors: tailoring defect densities in colloidal crystals using external fields
Saswati Ganguly, Surajit Sengupta, Peter Sollich
Coarse-graining atomic displacements in a solid produces both local affine strains and "non-affine" fluctuations. Here we study the equilibrium dynamics of these coarse grained qua…
