Shear-induced mixing of granular materials featuring broad granule size distributions
Joyjit Chattoraj, Nguyen Hoang Huy, Saurabh Aggarwal +2
Granular flows during a shear-induced mixing process are studied using Discrete Element Methods. The aim is to understand the underlying elementary mechanisms of transition from un…
Emergence of linear isotropic elasticity in amorphous and polycrystalline materials
Shivam Mahajan, Joyjit Chattoraj, Massimo Pica Ciamarra
We investigate the emergence of isotropic linear elasticity in amorphous and polycrystalline solids, via extensive numerical simulations. We show that the elastic properties are co…
Designing Phononic Band Gaps with Sticky Potentials
Yuanjian Zheng, Shivam Mahajan, Joyjit Chattoraj +1
Spectral gaps in the vibrational modes of disordered solids are key design elements in the synthesis and control of phononic metamaterials that exhibit a plethora of novel elastic…
Role of attractive forces in the relaxation dynamics of supercooled liquids
Joyjit Chattoraj, Massimo Pica Ciamarra
The attractive tail of the intermolecular interaction affects very weakly the structural properties of liquids, while it affects dramatically their dynamical ones. Via the numerica…
The stability phase diagram of active Brownian particles
Pin Nie, Joyjit Chattoraj, Antonio Piscitelli +3
Phase separation in a low-density gas-like phase and a high-density liquid-like one is a common trait of biological and synthetic self-propelling particles' systems. The competitio…
Frictional Active Brownian Particles
Pin Nie, Joyjit Chattoraj, Antonio Piscitelli +3
Frictional forces affect the rheology of hard-sphere colloids, at high shear rate. Here we demonstrate, via numerical simulations, that they also affect the dynamics of active Brow…
Noise Amplification in Frictional Systems: Oscillatory Instabilities
Joyjit Chattoraj, Oleg Gendelman, Massimo Pica Ciamarra +1
It was discovered recently that frictional granular materials can exhibit an important mechanism for instabilities, i.e the appearance of pairs of complex eigenvalues in their stab…
Oscillatory Instabilities in Frictional Granular Matter
Joyjit Chattoraj, Oleg Gendelman, Massimo Pica Ciamarra +1
Frictional granular matter is shown to be fundamentally different in its plastic responses to external strains from generic glasses and amorphous solids without friction. While reg…
