Glassy dynamics in two-dimensional ring polymers: size versus stiffness polydispersity
Rahul Nayak, Pinaki Chaudhuri, Satyavani Vemparala
Soft glassy materials often consist of deformable objects. Here, we use a two-dimensional assembly of semi-flexible ring polymers as a model system to investigate how polydispersit…
Activity-driven sorting, approach to criticality and turbulent flows in dense persistent active fluids
Suman Dutta, Pinaki Chaudhuri, Madan Rao +1
We show that dense active fluids comprising interacting particles with persistent self-propulsion are driven to a non-equilibrium steady state consisting of co-moving particles wit…
Cascade at local yield strain for silica and metallic glass
Nandlal Pingua, Himani Rautela, Roni Chatterjee +3
We report observations of unusal \emph{first} plastic events in silica and metallic glasses in the shear startup regime at applied strain two orders of magnitude smaller than yield…
Aging of ring polymeric topological glass formers via thermal quench
Arabinda Behera, Projesh Roy, Pinaki Chaudhuri +1
We investigate the dynamical response of glass-forming systems composed of topologically constrained ring polymers subjected to an instantaneous thermal quench, employing large-sca…
Athermal creep deformation of ultrastable amorphous solids
Pinaki Chaudhuri, Ludovic Berthier, Misaki Ozawa
We numerically investigate the athermal creep deformation of amorphous materials having a wide range of stability. The imposed shear stress serves as the control parameter, allowin…
Cooperative motion in equilibrium phases across two-dimension melting in pure and disordered systems
Saikat Dutta, Prashanti Jami, Pinaki Chaudhuri +2
We uncover the dynamics of particles with Gaussian core interactions across melting in pure and disordered two-dimensional (2D) systems. Intriguing signatures of cooperative motion…
