The effect of disorder on phases across two-dimensional thermal melting
Prashanti Jami, Pinaki Chaudhuri, Chandan Dasgupta +1
We study melting in a two-dimensional system of classical particles with Gaussian-core interactions in disordered environments. The pure system validates the conventional two-step…
Athermal quasistatic cavitation in amorphous solids: effect of random pinning
Umang A. Dattani, Smarajit Karmakar, Pinaki Chaudhuri
Amorphous solids are known to fail catastrophically via fracture, wherein cavitation at nano-metric scales is known to play a significant role. Micro-alloying via inclusions is oft…
Onset of glassiness in two-dimensional ring polymers: interplay of stiffness and crowding
Sayantan Ghosh, Satyavani Vemparala, Pinaki Chaudhuri
The effect of ring stiffness and pressure on the glassy dynamics of a thermal assembly of two-dimensional ring polymers is investigated using extensive coarse-grained molecular dyn…
Yielding in amorphous solids reveals an age-dependent intrinsic lengthscale
Aparna Sreekumari, Monoj Adhikari, Nandlal Pingua +5
Understanding how amorphous solids yield under shear is central to predicting material failure, yet prescribing reliable local yielding criteria remains a fundamental challenge. He…
Bidisperse ring polymers: topological glass to stacking
Projesh Kumar Roy, Pinaki Chaudhuri, Satyavani Vemparala
Via large-scale molecular dynamics simulations, we observe the melting of a topological glass of stiff ring polymers by incorporating flexible ring polymers, along an isobaric path…
Creep response of athermal amorphous solids under imposed shear stress
Suman Dutta, Kirsten Martens, Pinaki Chaudhuri
Yield stress materials fail when the imposed stress crosses a critical threshold. A well-known dynamical response to the applied stress is the phenomenon of creep where the cumulat…
