Effect of ring stiffness and ambient pressure on the dynamical slowdown in ring polymers
Projesh Kumar Roy, Pinaki Chaudhuri, Satyavani Vemparala
Using extensive molecular dynamics simulations, we investigate the slowing down of dynamics in a 3D system of ring polymers by varying the ambient pressure and the stiffness of the…
Universal mechanical instabilities in the energy landscape of amorphous solids: evidence from athermal quasistatic expansion
Umang A. Dattani, Smarajit Karmakar, Pinaki Chaudhuri
Using numerical simulations, we study the failure of an amorphous solid under quasi-static expansion starting from a homogeneous high-density state. During the volume expansion, we…
Residual stress in athermal soft disordered solids: insights from microscopic and mesoscale models
Vishwas V. Vasisht, Pinaki Chaudhuri, Kirsten Martens
In soft amorphous materials, shear cessation after large shear deformation leads to structures having residual shear stress. The origin of these states and the distribution of the…
Relaxation dynamics in the energy landscape of glass-forming liquids
Yoshihiko Nishikawa, Misaki Ozawa, Atsushi Ikeda +2
We numerically study the zero-temperature relaxation dynamics of several glass-forming models to their inherent structures, following quenches from equilibrium configurations sampl…
