On the existence of thermodynamically stable rigid solids
Customarily, crystalline solids are defined to be rigid since they resist changes of shape
determined by their boundaries. However, rigid solids cannot exist in the thermodynamic …

Nucleation theory for yielding of nearly defect-free crystals: Understanding rate dependent yield points
Experiments and simulations show that when an initially defect-free rigid crystal is subjected
to deformation at a constant rate, irreversible plastic flow commences at the so-called yield …

Degeneracy in molecular scale organization of biological membranes
SS Iyer, A Srivastava - Soft Matter, 2020 - pubs.rsc.org
The scale-rich spatiotemporal organization in biological membranes has its origin in the
differential inter-and intra-molecular interactions among their constituents. In this work, we …
