Athermal fluctuations in disordered crystals
Pappu Acharya, Surajit Sengupta, Bulbul Chakraborty +1
We analyze the fluctuations in particle positions and inter-particle forces in disordered jammed crystals in the limit of weak disorder. We demonstrate that such athermal systems a…
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…
Exploring the link between crystal defects and non-affine displacement fluctuations
Pankaj Popli, Sayantani Kayal, Peter Sollich +1
We generalize, and then use, a recently introduced formalism to study thermal fluctuations of atomic displacements in several two and three dimensional crystals. We study both clos…
Orientational correlations in fluids with quenched disorder
N. Shankaraiah, Surajit Sengupta, Gautam I. Menon
Snapshots of colloidal particles moving on disordered two-dimensional substrates can be used to extract equal-time many-body correlations in their positions. To understand the syst…
