Oscillatory Instabilities in 3-Dimensional Frictional Granular Matter
Silvia Bonfanti, Joyjit Chattoraj, Roberto Guerra +2
The dynamics of amorphous granular matter with frictional interactions cannot be derived in general from a Hamiltonian and therefore displays oscillatory instabilities stemming fro…
Transition from Static to Dynamic Friction in an Array of Frictional Disks
Harish Charan, Joyjit Chattoraj, Massimo Pica Ciamarra +1
The nature of an instability that controls the transition from static to dynamical friction is studied in the the context of an array of frictional disks that are pressed from abov…
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…
