Do thermodynamically stable rigid solids exist?
Parswa Nath, Saswati Ganguly, Jürgen Horbach +3
Customarily, crystalline solids are defined to be {\em rigid} since they resist changes of shape determined by their boundaries. However, rigid solids cannot exist in the thermodyn…
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…
Pre-yield non-affine fluctuations and a hidden critical point in strained crystals
Tamoghna Das, Saswati Ganguly, Surajit Sengupta +1
A crystalline solid exhibits thermally induced localised {\em non-affine} droplets in the absence of external stress. Here we show that upon an imposed shear, the size of these dro…
