Activated solids: Spontaneous deformations, non-affine fluctuations, softening, and failure
Parswa Nath, Debankur Das, Surajit Sengupta +1
Internal activity can fundamentally reshape the mechanical behavior of solids, yet its role in softening and failure remains incompletely understood. In this study, we investigate…
Neutral atom scattering based mapping of atomically thin layers
Geetika Bhardwaj, Krishna Rani Sahoo, Rahul Sharma +2
Imaging surfaces using low energy neutral atom scattering is a relatively recent development in the field of microscopy. In this work we demonstrate that this technique is sensitiv…
A nucleation theory for yielding of nearly defect-free crystals: understanding rate dependent yield points
Vikranth Sagar Reddy, Parswa Nath, Jürgen Horbach +2
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-call…
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…
Equilibrium and dynamic pleating of a crystalline bonded network
Saswati Ganguly, Jürgen Horbach, Peter Sollich +3
We describe a phase transition that gives rise to structurally non-trivial states in a two-dimensional ordered network of particles connected by harmonic bonds. Monte Carlo simulat…
